a couple of my fingers have been really hurting lately, they kinda feel like they are very bruised and when i touch the knuckle it feels like i just slammed my fingers in a door ... sometimes when i touch these fingers i get sharp pain as if the bones were in shards or something. i don't know how to explain this. i have this in two fingers and one of my fingers is curving at the top joint. is this osteoarthritis? i have OA in my spine and knees, but haven't a clue if this constitutes OA in my fingers. heaven forbid i bump those knuckles doing something AAAggggghhhhhhh!
