Cushion your elbows. Buy elbow/heel pads at a drug store and use them. Even though it may not be specifically related to TFS, the ulnar nerve runs very close to the surface in people's elbows. If they bang around on them, rest on them too much, etc. (usually not noticed) then the nerve gets irritated and can cause all kinds of pain etc. down just the little finger and one vertical half of the ring finger, the one closest to the little finger. Cushioning the elbows helps to alleviate this.

It sounds and looks kind of funny at first, but I went through all kinds of occupational tests to determine that I was bumping my elbows and then irritating the damage even more by being on the computer so much. Once I knew what the cause was I started paying attention and darn if I wasn't doing just as they said! Wearing the pads really helped a bunch and it was a very inexpensive aide.

Good luck!
