I have noticed that after a wing session, my left index finger is sore. Closest analogy is how your finger feels after getting "jammed" while catching a football. Not super painful but kind of stiff and sore, especially when trying to bend it down all the way to touch the base of my thumb. My right index is fine, and I'm going both ways equally frequently.
I've been trying to diagnose what could be causing it, I thought maybe it's my hand spread while getting up, but it never feels like I am straining it or anything when doing that. Somehow I think it's related to movements while I'm bringing the wing to air while getting up with one hand on the front loop, but even while thinking about it while riding I cant isolate any action that would trigger it.
I'm basically asking, "Has anyone else experienced this and if so did you modify any aspect of your movements to alleviate?"
