When I was cleaning my ipad with a cloth I notice that my middle finger and my ring finger were stuck in a potion that was hard to undo.It was like the bones were rubbing against each other hard.It's the same with my thumb I think because I did to much croshay.i can hear it when my thumb does I though.. I'm only 13.
Is there a exercise or something that could undo it. And could u tell me the reason of why this occurs is it really bad. I am really worried.
