While CTS is known to be a problem in the wrist, this is quite often a symptom of what is taking place elsewhere. Due to the carpal bones and strong connective tissues of the wrist, swelling in this area of the body called the carpal tunnel doesn’t allow for expansion as in other areas of the body.
The result is that the nerve that runs through this tunnel is compressed and causes pain, numbness, and tingling. The reason for the swelling, however, may be due to problems further up in the arm. If the normal lymphatic drainage is inhibited in the upper rib cage, shoulder or anywhere along the arm, this backup of fluid can result in the symptoms as described above.
Restoring flow to the blood, lymph, and all the tissues can reverse the restriction, decrease the swelling, and stop the symptoms.
