CTS *does* have to do with the tendons. It is the movement of tendons within their sheaths as fingers flex that cause this repetetive strain disorder. Friction, then irritation, then swelling of the tendons leads to the compression of the media nerve. A compressed media nerve leads to the symptoms. Everyone experiences a little bit of this, tingling and numbness, but as long as the compression is minor no permanent damage is done. If the nerve gets badly crushed, CTS can become a debilitating condition.
