Application Of Heat Or Cold
Applying heat or cold seems to relieve pain and may accelerate the repair process.
Cold reduces pain and swelling and is recommended for injuries and inflammations . The use of ice it is not recommended in case of muscle pain because cold temperature will contract the muscle even more. Application of ice on painful muscle is recommended only immediately after an injury occurred, and only for few days.
Heat is recommended for muscle pain relief. Heat increases the flow of blood which facilitates the elimination of lactic acid build up. It is not recommended for injuries with significant inflammation and swelling.

Other Preventative Techniques For Carpal Tunnel Syndrome Include:
- Accurate Monitoring and treating scientific stipulations linked to this Carpal tunnel syndrome.
- Performing conditioning and stretching workout routines earlier than and after activities.
- Taking short strolls and breaks
- Taking regular relaxation breaks from repetitive movements.
- Abstaining from flexing or curling and extending wrists repeatedly
- Avoid repetitive solid actions with the wrist in a flexed position
- Keeping wrists straight when using tools or performing activities.
- Keeping wrists in a straight place when sleeping.
Immediately After Surgery For Carpal Tunnel Syndrome
After the operation, you can expect that:
- If you had a general anaesthetic, nurses will check your temperature, pulse, breathing, blood pressure and wound site frequently.
- You should not eat anything for at least four hours after the operation.
- Your wrist may be placed in a sling to help reduce swelling.
- Your wrist may be quite painful or uncomfortable for a couple of days. Your doctor will order analgesia .
- You should exercise your hand and wrist as soon as possible, following your doctors advice.

Conventional Carpal Tunnel Release
Surgical decompression of the carpal tunnel via transection of the flexor retinaculum was first described by Sir James Learmonth in 1933, and multiple series since have reported patient satisfaction rates of 70% to 96% with the procedure.41 The goal of surgery is to successfully divide the TCL and decompress the median nerve while preserving its recurrent motor and palmar cutaneous branches. The traditional open carpal tunnel release is performed using loupe magnification with the patient under locally injected anesthesia with or without mild sedation in an outpatient operating room setting. With the patient positioned supine, the affected arm is abducted and the forearm is supinated on a hand table or an arm board without the use of a tourniquet . Following a sterile prep and drape, the incision begins at the distal wrist crease and extends 3 to 4 cm distally in a curvilinear fashion parallel with and approximately 2 mm ulnar to the midpalmar crease . The incision ends at or near the level of the distal border of the thumb and may be extended proximally, if necessary, for about 1 cm to create an S-shaped incision. Care must be taken to avoid sectioning branches of the palmar cutaneous nerve during the proximal segment of the skin incision. With experience, the entire incision may be minimized to anywhere from 1.5 to 3 cm in length and still allow for complete division of the TCL .
How Is Carpal Tunnel Syndrome Treated
Treatments for carpal tunnel syndrome should begin as early as possible, under a doctor’s direction. Underlying causes such as diabetes or arthritis should be treated first.
- Splinting. Initial treatment is usually a splint worn at night.
- Avoiding daytime activities that may provoke symptoms. Some people with slight discomfort may wish to take frequent breaks from tasks, to rest the hand. If the wrist is red, warm and swollen, applying cool packs can help.
- Over-the-counter drugs. In special circumstances, various medications can ease the pain and swelling associated with carpal tunnel syndrome. Nonsteroidal anti-inflammatory drugs , such as aspirin, ibuprofen, and other nonprescription pain relievers, may provide some short-term relief from discomfort but havent been shown to treat CTS.
- Prescription medicines. Corticosteroids or the drug lidocaine can be injected directly into the wrist or taken by mouth to relieve pressure on the median nerve in people with mild or intermittent symptoms.
- Alternative therapies. Acupuncture and chiropractic care have benefited some individuals but their effectiveness remains unproved. An exception is yoga, which has been shown to reduce pain and improve grip strength among those with CTS.
Recurrence of carpal tunnel syndrome following treatment is rare. Less than half of individuals report their hand feeling completely normal following surgery. Some residual numbness or weakness is common..

Median Nerve Microcirculation Injury
Ischemic vascular injury and the breakdown in the blood-nerve barrier have also been identified as an essential component in CTS. The blood-nerve-barrier is formed by the inner cells of the perineurium and the endothelial cells of endoneurial capillaries that accompany the median nerve through the carpal tunnel. These endoneurial microvessels are formed from nutrient branches that arise from the radial and ulnar arteries, proximal to the flexor retinaculum. An increase in pressure within the tunnel can cause a breakdown of vasculature within this barrier, causing an accumulation of proteins and inflammatory cells. This may induce a miniature closed compartment syndrome by increasing the permeability, contributing to increased endoneurial fluid pressure and development of an intra-fascicular edema. Patients with vascular problems or prolonged exposure to static loading are particularly prone to a breakdown in the blood-nerve-barrier.
MacKinnon and coworkers have also described common progressive neurovascular changes occurring in a series of experimental studies looking at histological findings at common sites of entrapment.- These included early perineurial and endoneurial microvessel thickening with basement membrane reduplication, Renauts body formation, perineurial and epineurial fibrosis, and patchy fibre loss associated with thinning of myelin, attributed to fibre demyelination and degeneration.
Treatment For Carpal Tunnel Syndrome
Depending on the severity of your carpal tunnel syndrome, your physician may recommend the following:
- Occupational therapy to loosen the tendons in the hands and wrists
- Nonsteroidal-anti-inflammatory drugs, such as aspirin, ibuprofen, and other nonprescription pain relievers to help reduce pain and inflammation
- Splints to help immobilize the wrist
- Resting the hands and wrist for longer periods throughout the day
- If more conservative approaches do not help the pain and dysfunction, your doctor may recommend surgery such as carpal tunnel release to relieve pressure on the nerve.

Median Nerve Connective Tissue Alterations
Nerve fibres have layers of connective tissue surrounding it. These layers are the mesoneurium , epineurium, perineurium, and endoneurium which is the most intimate layer. The extensibility of these layers is critical to nerve gliding , which is necessary to accommodate joint motion otherwise, nerves are stretched and become injured. It is estimated that in normal subjects, the median nerve at the wrist can move up to 9.6 mm between full flexion and extension of this joint but in the presence of stiff surrounding connective tissue, this is limited and exposes the nerve to shearing forces that could lead to injury.
The longitudinal movement of the median nerve in the carpal tunnel was found to be 9.6 mm during flexion, and 0.7-1.4 cm in wrist extension. It can vary from 2.5 to 19.6 mm depending on the position of the shoulder, elbow, wrist, and fingers. The median nerve tension varies from 8% depending on the position of the shoulder, and 19% depending on the position of the fingers. In addition to the longitudinal movement, a transverse movement of the median nerve occurs with wrist position or during finger flexion against resistance. In compression and epineural adhesions, mobility is hindered, creating lesions due to repeated traction on the nerve during wrist movements.

Carpal Tunnel Syndrome Vs Cervical Radiculopathy
Carpal tunnel syndrome is not the only condition that can cause numbness and tingling in the hands and wrists. These symptoms can also be caused by problems in the cervical spine.
Watch: Cervical Spine Anatomy Video
Conditions such as a herniated or degenerated disc, cervical stenosis, or cervical osteoarthritis can trigger impingement on the C6 or C7 nerve roots, which originate in the cervical spine and innervate almost the same areas of the hand as the median nerve.
See C6-C7 Treatment
Because theyre both conditions caused by nerve impingement, both carpal tunnel syndrome and cervical radiculopathy cause similar symptoms: dull pain, tingling, and/or numbness, with occasional shooting pains along the nerve path.
A comprehensive neurological evaluation can help identify whether the symptoms are being caused by carpal tunnel syndrome or a cervical spine condition. In fact, sometimes the two conditions are seen together, as nerve compression at the neck can make the nerves lower down more vulnerable. Clinical evaluation, electrodiagnostic testing EMG, and possibly neck imaging can help put together the pieces of the puzzle.
How Can We Prevent Carpal Tunnel Syndrome
Prevention of carpal tunnel syndrome may involve redesigning work stations, tools, or the job, and educating workers. Proper work station design reduces awkward wrist positions and minimizes the stressful effects of repetitive motions. Awkward positions can originate from unsuitable work station designs that do not take into account the size and proportions of the human body. Work stations should be adjustable and should accommodate a vast majority of people who work in that area.
Redesigning work methods is important. For example, using an adjustable fixture to hold an electrical housing, as Figure 3 shows, reduces wrist flexion.

Medical treatment of both conditions emphasizes conservative approaches, including rest from offending activities and splints to reduce aggravation of the nerve. Splints are especially helpful at night during sleep when the wrist or elbow may be held in detrimental positions for long periods.
Because Guyons canal syndrome is caused by external compression, reducing the external compressive force is usually sufficient treatment, although healing may be slow. In cubital tunnel syndrome, surgery may be necessary if conservative treatment is ineffective.
Massage therapists should avoid any techniques that cause further nerve compression, evident by an immediate increase in symptoms. In Guyons canal syndrome, there is no prominent role for massage therapy because most massage techniques would incorporate some degree of compression over the canal, which could irritate symptoms. Massage of the entire upper extremity, however, can certainly help reduce the detrimental effects of distal neural compression, so working the entire upper extremity and being careful about any symptom increases is a helpful approach.
Basics Of Carpal Tunnel Syndrome
Carpal tunnel syndrome is a condition that can cause pain, tingling, numbness, and weakness in the fingers and thumb. Specifically, carpal tunnel syndrome is the compression of the median nerve located in the wrist. This nerve supplies feeling to the thumb, index, middle and ring finger. The carpal tunnel is a well defined space in the palm at the wrist. The two walls of this anatomical tunnel are formed by bones that support the wrist. The roof of the tunnel is the thick transverse carpal ligament. Several tendons and the median nerve pass through this tunnel. Space in the tunnel decreases when tendons swell or the ligament thickens. Pressure inside the tunnel increases and restricts blood flow to the nerve. The pressure is most noticeable when the wrist is fully extended or flexed.

Carpal Tunnel Syndrome At A Glance
Carpal tunnel syndrome occurs when a nerve is pinched in the carpal tunnel. This nerve is responsible for several areas of your hand and if it is permanently pinched, symptoms arise. These include, for example, pain, sensations such as tingling and, in the later stages, paralysis.
Initially, the symptoms are reminiscent of an acute tendonitis, but this disappears after a while. Permanent constriction in the carpal tunnel can cause the symptoms of chronic tendonitis of the hand to develop.
The carpal tunnel is located in the wrist. The median nerve, the middle arm nerve, runs through its center. It begins in the shoulder, runs down the upper arm, and finally enters the hand. It is responsible for muscle movement and the sense of touch in the hand.
If the carpal tunnel is narrowed, the nerve becomes pinched and thus permanently irritated. The discomfort is sporadic at first but manifests itself quickly. You should therefore see a doctor in good time because in the early stages therapy is often possible by splinting the wrist.
Ignoring Symptoms Of This Carpal Tunnel Syndrome Can Lead To Permanent Nerve Damage
First, you may notice tingling or numbness in your fingers that comes and goes. Over time, the sensations may get worse, lasting longer or even waking you up at night. Eventually the pain and numbness might even make it hard to grip things like a fork, a pen, or other objects.
If you’re having these symptoms, it could be carpal tunnel syndrome, which occurs when the median nerve which runs down your arm and into your hand is compressed by a ligament that crosses over it as it passes through a narrow space in the wrist known as the carpal tunnel.
“Carpal tunnel syndrome has classic symptoms, which include numbness and tingling in the thumb, index finger, middle finger, and half of the ring finger,” says Dr. Tamara Rozental, professor of orthopedic surgery at Harvard Medical School and chief of hand and upper extremity surgery at Beth Israel Deaconess Medical Center. Your little finger is typically not affected because a different nerve serves it.

Conditions We Treat: Carpal Tunnel Syndrome
Carpal tunnel syndrome is a condition of nerve entrapment caused by the narrowing of the tunnel surrounding the tissues inside the bones of your wrist, inflaming the median nerve and surrounding tissues. The median nerve gives feeling to your thumb, and index, middle and ring fingers. People engaged in repetitive hand motions throughout their day may develop carpal tunnel syndrome.
When To Get Surgery
“The mistake that people often make is waiting too long to get surgery,” says Dr. Rozental. “I see a lot of people who say that their numbness was gradually worsening and now their hand is completely numb and has been for a year.” If the nerve is compressed long enough, the muscle atrophies and the nerve damage becomes permanent, she says.
So, if your carpal tunnel symptoms aren’t responding to other treatments, take action quickly.
The surgery takes 10 minutes under a local anesthetic. Unless you do a job that involves manual labor, you can typically go right back to normal activities, says Dr. Rozental.
“I tell my patients all the time that a carpal tunnel release done at the right time for the correct diagnosis is very successful,” she says.

How Often Is Hand Pain Caused By Carpal Tunnel Syndrome
While carpal tunnel syndrome is a common condition, it has a different set of symptoms from many other sources of hand pain. There are actually several similar conditions that cause hand pain. These include:
- De Quervains tendinosis: A condition where swelling affects the wrist and base of the thumb. In this condition, you will feel pain when you make a fist and simulate shaking someones hand.
- Trigger finger: This condition causes soreness at the base of the finger or thumb. Trigger finger also causes pain, locking and stiffness when bending the fingers and thumb.
- Arthritis: This is a general term for many conditions that cause stiffness and swelling in your joints. Arthritis can impact many joints in your body and ranges from causing small amounts of discomfort to breaking down the joint over time .
Other Conditions Which May Be Misdiagnosed As Cts
Carpal tunnel syndrome is frequently misdiagnosed due to the fact that it shares symptoms with several other conditions, including arthritis, wrist tendonitis, repetitive strain injury and thoracic outlet syndrome. Symptoms which CTS shares with other conditions include:
- Hot-and-cold sensations
- Difficulty grasping or using oneÃ¢â¬â¢s hand
It is important to be aware of the key differences between CTS and some other conditions which share its symptoms, in order to avoid a misdiagnosis. Other conditions which are commonly misdiagnosed as CTS include:
Arthritis can affect all the fingers in the hand, whereas CTS cannot affect the little finger. Whereas CTS is worse at night, arthritis is not affected by the time of day. The symptoms of CTS can be absent and then suddenly become triggered by a particular activity, whereas the pain associated with arthritis is usually constantly present but alters in intensity during activities which put strain on the hands and wrists.
Nerve compression due to conditions affecting the spine
Conditions such as spinal disc herniation and cervical stenosis can cause nerve compression that may result in similar sensations to those of CTS.
