One of the primary culprits for causing interference with the movement of the nervous system seems to be inflammation and the ensuing fibrotic changes around and within the nerve involved. Repetitive movements causes irritation and inflammation and swelling of the tissues surrounding the nerve and if it advances the inflammation can get into the nerve sheath. This process can be progressive with subsequent bouts of pain and tissue damage or irritation, inflammation and fibrotic changes. Often the fibrotic changes and lack of normal movement in and around the nerve seem to perpetuate the problem. It is important to remember that a little prevention and maintenance exercise can go a long way to keeping repetitive strain injuries from becoming a big problem.
Most people are aware of the benefits of stretching.
Just as hamstring stretching not only stretches the muscles but also moves the sciatic nerve. Stretching of the arms in a certain ways can help to maintain the muscle length and normal mobility of the nerves. Here is an exercise to try next time your arms or hands start to ache or get mildly tingly. If you have severe pain, numbness, tingling or weakness you should get proper help. Stand and place the palm of your hand against the wall with the fingers facing the ceiling, or for a stronger mobilization, with the fingers facing backwards.
