How Does Carpal Tunnel Syndrome Develop
Bending the wrist or moving the fingers brings muscles and tendons into action. For example, when a person bends a finger, the tendon moves about two inches. The tendons of the hand are encased in sheaths, or sleeves through which the tendons slide. The inner wall of the sheaths contains cells that produce a slippery fluid to lubricate the tendons. Lubrication is essential for the normal and smooth functioning of the tendons. With repetitive or excessive movement of the hand, the lubrication system may malfunction. It may not produce enough fluid or it may produce a fluid with poor lubricating qualities. Failure of the lubricating system creates friction between the tendon and its sheath causing inflammation and swelling of the tendon area. In turn, the swelling squeezes the median nerve in the wrist or carpal tunnel. Repeated episodes of inflammation cause fibrous tissue to form. The fibrous tissue thickens the tendon sheath, and hinders tendon movement.
How Can Carpal Tunnel Syndrome Be Prevented
Carpal tunnel syndrome can be difficult to prevent. The condition can be caused by so many different activities in a persons daily life that prevention can be challenging. Workstation changesproper seating, hand and wrist placementcan help decrease some factors that can lead to carpal tunnel syndrome. Other preventative methods include:
- Sleeping with your wrists held straight.
- Keeping your wrists straight when using tools.
- Avoiding flexing and extending your wrists repeatedly.
- Taking frequent rest breaks from repetitive activities.
- Performing conditioning and stretching exercises before and after activities.
- Monitoring and properly treating medical conditions linked to carpal tunnel syndrome.
Diseases Of The Thyroid
People with improperly-managed thyroid conditions may retain excess fluid in their connective tissues. This contributes to inflammation within the wrist, which can cause CTS, especially if left untreated. Hypothyroidism is particularly linked to CTS, but people with hyperthyroidism are also more likely to develop CTS than the general population.

Carpal Tunnel Syndrome Faqs
Q: Does typing cause CTS?A: Typing is associated with an increased likelihood of developing repetitive strain injury . If RSI affects the tendons or ligaments in the carpal tunnel, this can cause compression on the median nerve and the development of CTS. However, research has shown that there is at most a very small direct link between computer work and CTS. Activities which involve using the hands and wrists with a greater intensity, such as using vibrating tools, are significantly more likely to cause CTS than typing. The use of ergonomic computer keyboards is, however, sometimes recommended as a preventative measure against developing CTS.
Q: Can children be affected by CTS?A: CTS in children is rare. When it develops, it is most commonly related to having a genetically inherited condition associated with inflammation, such as lysosomal storage disease, which can cause swelling in the joints and pressure to build up in the carpal tunnel. The symptoms of CTS and its treatment options are the same for children as for adults. If you are concerned that your child, or a child that you know, may be affected by CTS, you can get a free symptom assessment by downloading the Ada app.

Treatment For Severe Symptoms
If symptoms persist for more than 6 months and are interfering with your daily life and work activities, despite self-care and treatment, you may need surgery. Surgery relieves pressure on the trapped nerve and aims to prevent any permanent nerve damage. Your doctor will be able to discuss the most suitable method of surgery with you.
The Median Nerve: The Most Important Part Of Carpal Tunnel Syndrome Anatomy
The most essential component of Carpal Tunnel Syndrome anatomy is the median nerve. This important nerve begins as part of the brachial plexus of nerves. It originates at the neck, passes under the collarbone and across the front of the shoulder.
At the front of the shoulder, the brachial plexus divides forming the three separate nerves: median, ulnar and radial. From that point on, the median nerve is considered a separate entity in the anatomy of the arm.
The median nerve pathway continues down the arm, passing through a seam of fascia between the biceps and triceps muscles on the inside of the upper arm. It then travels through the elbow area, and down the inside of the forearm into the wrist and hand. Ultimately, the median nerve terminates in the thumb, index and middle fingers.
The median nerve is responsible for bringing feeling to the palm side of the hand and wrist, the thumb, the index and middle fingers and sometimes to part of the ring finger.

Treatment: Rest And Immobilization
Underlying causes such as diabetes or arthritis will need treatment. Then your doctor may advise resting the hand and wrist and wearing a brace to limit movement. Night use is important to prevent the wrist from curling during sleep, which can make symptoms flare up. Non-steroidal anti-inflammatory drugs such as ibuprofen and naproxen, along with cold compresses, may reduce pain.
If You Are Experiencing Pain In Your Hands Or Wrists You May Be Experiencing Symptoms Of Either Carpal Tunnel Syndrome Or Trigger Finger Certain Symptoms Differentiate The Two Conditions And Dictate The Course Of Treatment
Carpal tunnel syndrome and trigger finger both affect your hand causing pain, stiffness, and reduced ability to work or manipulate objects. While both conditions affect your hands, carpal tunnel also affects the wrist, forearm, and selected fingers. This extends your pain, numbness, and weakness.
Trigger finger targets a sole finger or thumb, locking the joint uncomfortably into place and making even simple movements difficult. If you are experiencing excessive pain or stiffness, discuss your pain management options with your doctor. An orthopedic surgeon can correctly diagnose and treat the symptoms of either carpal tunnel or trigger finger.
What Is Carpal Tunnel Syndrome?The ability to move your hand and feel sensations in your thumb and first three fingers is directly connected to the median nerve. This pathway runs from your forearm to your hand via a small tunnel in your wrist the carpal tunnel.
When this pathway is compromised, from either illness or repetitive motion, your median nerve is put under pressure resulting in tingling, weakness, and numbness in your hands, wrists, and arms. Common signs of carpal tunnel syndrome include pain in the thumb and first three fingers .
Do I Need Carpal Tunnel Surgery?Mild or first-time symptoms can be treated with rest and over-the-counter pain relievers. Using ice packs and wearing a wrist splint to stabilize your hand and arm at night can also reduce the pressure and alleviate your symptoms.

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 .
The Carpal Solution Is Self
There is an old adage that gentle pressure consistently applied is the key to solving most problems in life. This describes the power behind Carpal Solution Therapy. Over the Six Week Protocol The Carpal Solution puts Carpal Tunnel Syndrome into remission naturally and non-invasively without the risky outcomes and long rehabs associated with surgery, the complications of oral pain medication or the downside of steroid injections or the risk of muscle atrophy so common with conventional rigid hand braces and restrictive splints.
Carpal Solution combines gentle soft tissue stretching and reshaping at night during sleep with active use during the day. This results in an ideal rhythmic therapy for rapid relief from Carpal Tunnel symptoms with no muscle atrophy or down time and no limitations from restrictive braces. The hand rehabilitates through normal use once pain is relieved and free movement is restored. It is well know among muscular skeletal specialists that muscle atrophy from rigid wrist braces and hand splints can severely complicate recovery from Carpal Tunnel Syndrome.
Be that as it may, however, if you suspect that you do have some form of RSI, not only should you discuss your hand condition with a qualified medical professional, but you should also look into ergonomic workstation improvements and posture and day time stretching. A better ergonomic keyboard set-up, for instance, can complement the Carpal Solution in reducing minimizing flare-ups.

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.
When Should I Call A Doctor
Anytime you have any of the common symptoms of carpal tunnel syndrome on a regular basis. When you get care early on, you may find that basic options, such as rest or wearing a wrist brace, work well. Thatâll allow you to avoid more serious treatment like surgery. Without any treatment, your symptoms could become permanent.

Finger Numbness And Finger Pain
Finger numbness and finger pain are both telltale signs of Repetitive Stress Injury and often are associated with carpal tunnel syndrome . If you are experiencing even temporary finger numbness and or finger pain or numb hands or pain in your hands and extremities, it would be wise to take action to prevent these symptoms from developing into a chronic syndrome. A proactive, full-spectrum approach to treating repetitive strain injury is your best defense against chronic, persistent, potentially debilitating pain.
It is hard to imagine for most people, that gentle keystrokes on a computer keyboard and subtle finger action on a musical instrument could ever result in serious injury to the hand.However, bear in mind that the numbness and tingling you may be experiencing is likely the combined result of thousands or tens of thousands of delicate, but repeated hand and finger motions.
The cumulative effective over decades results in wear and tear that creates CTS.
Chronic RSI sufferers may not respond to traditional treatment methodologies such as ibuprofen, stiff wrist splints, cortisone injections, and Carpal Tunnel Surgery and often experience unwanted side effects and complications. For a repetitive strain related injury the symptoms almost always return, so it is important to identify a natural therapy without downtime or complications to relieve the symptoms non-invasively.

Conditions With Symptoms Similar To Carpal Tunnel Syndrome
Other conditions, including different types of nerve compression, can look like carpal tunnel syndrome. Some of these are:
- Arthritis.Arthritis of the wrist can cause many of the same symptoms. One key difference is that arthritis may cause visible swelling and redness.
- Cubital tunnel syndrome. Also called ulnar tunnel syndrome, this condition is due to compression, or squeezing, of the ulnar nerve in the elbow. Symptoms are more likely to affect the pinkie, ring finger, and inside of the hand.
- Pronator syndrome.Pronator syndrome is a condition in which the median nerve in the arm is compressed. Pain is typically felt in the arm but can extend to the palm, making it difficult to make the OK sign.
- Radial tunnel syndrome.Radial tunnel syndrome is due to compression of the radial nerve, which runs from the neck through the arm. It rarely causes the numbness or tingling of carpal tunnel syndrome. Pain is more likely to occur in the forearm or back of the hand.
- Tendonitis.Tendonitis of the wrist is due to inflammation of the tendons. Unlike carpal tunnel syndrome, tendonitis may cause swelling, and the pain tends to improve with rest.
What You Need To Know
- Carpal tunnel release is one of the most common hand conditions requiring surgery.
- Symptoms may include tingling, pain, numbness or weakness in the thumb through ring fingers of the affected hand.
- Women get carpal tunnel syndrome three times more often than men.
- Carpal tunnel syndrome is a progressive condition that can worsen without proper care.

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.
Research And Possible Risk Factors
Researchers have found that a previous wrist fracture and the use of insulin, metformin, and sulphonylureas are associated with a higher chance of CTS. Smoking, hormone replacement therapy , the combined oral contraceptive pill, and oral corticosteroids did not appear to be not linked to a higher risk of CTS.
One study has suggested that obesity, combined with a square-shaped wrist shape, may increase the likelihood of CTS developing. However, the team concluded that obesity was probably not the cause, because when participants with obesity lost weight, they continued to have CTS.
The same team concluded in other research that the age of women at the menopause might be a factor, and that pregnancy-related hormones may increase the risk of CTS in women at the time of the menopause.
Apart from work-related factors, the main risk for CTS is inflammatory arthritis, but hypothyroidism and diabetes also appear to increase the chance of developing it, according to research published in the Journal of General Internal Medicine.
The National Institute of Neurological Disorders and Stroke says that CTS is three times more likely to occur among people working in assembly operations than in data-entry personnel.
The Canadian Centre for Occupational Health and Safety list the following occupations as risk factors for CTS:
