My doctor diagnosed my wrist pain really strangely and I'd love a second opinion

[Dheathwilliams]

Hi! I'm 23 years old and work at a computer all day, come home and play guitar/craft a guitar for the rest. Recently I've done a lot of precision sanding that took a while.

I started to notice when I straighten my right elbow, fingers out, and twist so the palm is up, I feel pretty bad pain in the inside (thumb side) of the wrist. (the same pain happens when I just pinch the thumb and fingers and straighten) I also noticed if i massage the base of my bicep near the elbow, I can send a shooting feeling up to that same pain location.

I had no numbness in any of my fingers, but the pain was getting worse, so I took it to an orthopedic specialist. The doctor felt the tendon in my elbow and said that seemed fine and moved my thumb around.

He didn't diagnose any repetitive injury with the median nerve, as I expected him to, but instead said somehow I damaged the lateral antebrachial cutaneous nerve.

From what I've read this is a pretty rare phenomenon usually caused by some extreme form of hyper extension, of which I don't recall having occurred.

Additional details: two months ago I mildly fractured the 5th metacarpal right in the middle, it healed fine, I figured it wasn't related.

Should I seek another opinion? Any suggestions? I really like to soon be able to continue my work.

Thanks!
