Piano Answers

My wrist seems like it is sprained, it hurts whenever I bend it to a certain point, & it’s somewhat swollen. It is not discolored though, & I don’t have any idea how i might have sprained it.
I’m normally an active guy, but in the past month or so all i’ve been doing is running, pushups, & situps. I got my computer back last week(it was being repaired for several monthes) & I spent a good time over the weekend playing piano, which i haven’t done in several months either, but I really doubt that either of those would give me any type of overuse injury, especially in one hand.
thanks!
