Ok, I know no one is actually going to be able to diagnose me, but I'm curious if anyone else has experience of this. I broke my finger a few years ago, and it didn't heal totally straight (very subtle extra bump by the joint, no one else would be able to tell). No issues with it since until this week when it has started hurting. No new injury, no difference in usage, just a bit sore, particularly when straightening it. I think there may be a very subtle change where the extra bump is but it's difficult to tell. Is it possible for an old injury to do this several years on? Is there anything I can do to help it? Very difficult to rest/strap a finger!
