It's getting on this last nerve that is causing it to cry out in pain. Normally, the tenosynovium should slide back and forth, but when the tendons become inflamed, pressure in the carpal tunnel builds until the median nerve, the softest tissue in this space, suffers from crowding. After a while, the pressure reaches the point where the nerve stops functioning normally and numbness results. You could also be genetically predisposed to CTS, as some people's tendons are not as slippery as other people's. Folks with other medical conditions such as gout, diabetes, rheumatoid arthritis, and alcoholism seem to be more susceptible to CTS, as are women experiencing hormonal changes.
Job stress seems to be another factor.
Okay, you big baby. Following that disclaimer, there are some things you can do yourself if you catch the problem early enough. Probably the most common treatment is to wear a simple wrist-splint. This is a soft, cast-like wrapping that keeps your wrist from bending. In this position, the carpal tunnel is as big as it can be.
