Loss of full motion in thumb
I was attempting to scratch my lower middle back with my thumb and I felt a little pop about midway up my forearm. Now my thumb won't fully extend in, for instance, the hitchhiker's pose. I can still grip with it, and there's no pain, but I can no longer extend it.
Any thoughts would be greatly appreciated.

Sounds like a possible EPL
Sounds like a possible EPL tear. The EPL (Extensor Pollicus Longus) is a primary extensor muscle of the thumb. When it is torn, you no longer are able to extend the thumb, but you are able to flex (bend) it no problem.
Treatment for this is surgery to reconnect the severed tendon. Approx. 8-12 week recovery period.
