Merry Christmas ponygirl!
None of my business, and I don’t know if I’ve been following everything on your elbow, but have you considered one of those vertical mice for your computer so your palm is facing inward instead of down? It’s helped me...
Yes, I've been using a vertical mouse for a while and it definitely helps, but it turned out that my desk and chair were the problem. I was using an adjustable height desk that gave me very limited 6x6 inch space for "mousing," and the limited area plus working 10-12 hour days at that time really kind of screwed up my elbow. So I got a new desk setup out of the deal and bought myself a new Henry Miller chair. Now I also switch between the vertical mouse and a Wacom tablet to change up my hand position.
