Repetitive Strain Injuries (RSIs) can happen to anyone whose work calls for long periods of steady hand movement, from musicians & dental hygienists to meat cutters & cashiers. RSIs tend to come with work that demands repeated grasping, turning and twisting; they are especially likely if the work requires repeated twisting or involves repetitive vibration, as in hammering nails or operating a power tool. Stressful hand, arm and neck positions — whether from working at a desk, long-distance driving or waiting on tables — only aggravate the potential for damage.

A number of sports can bring on repetitive stress injuries. The obvious sports associated with these ailments include both Tennis Elbow as well as Golfers Elbow. Just about any activity that involves repetitive movement, including rowing, skiing, archery, etc. can lead to injury.

The above mentioned sports represent just a sampling of activities that stress the hand and wrist joints. Injuries and ailments that cause swelling or compression of soft tissue on nerves, such as sprains, leukemia, and rheumatoid arthritis can lead to stress injuries too.

Diabetes, thyroid problems, and other systemic disorders are also associated with discomfort from stressed nerves, as is the fluid accumulation that sometimes accompanies pregnancy. Some authorities believe that a pyridoxine (vitamin B6) deficiency can also induce the symptoms.

Fluid retention, a major contributor to CTS & RSI symptoms naturally occur with the usage of contraceptive pills. Post Menstrual Syndrome (PMS) also causes fluid retention as do many other medical conditions, all of which can result in Carpal Tunnel Syndrome symptoms.

• A tingling or numb feeling in the hand and/or fingers;

• Shooting pains in the wrist or forearm, and sometimes extending to the shoulder, neck and chest, or foot;

• Difficulty clenching the fist or grasping small objects;

For many unfortunate sufferers, CTS has a pattern of flaring up through the night thereby making sleep difficult. CTS symptoms can also be expected to arise frequently while performing the activity that is the cause of the condition in the first place.
