I have similar thing. Went for an interception and the sun blinded me, ball bounced off my pinky, the first joint. I can move it now and grip it however my first joint is swollen like a mfthka. I think its just alot of pus stored inside.Tried to get a dr. appt but found out he is booked for two weeks, WTF?! anyways yea its been a month and its still swollen just got to wait for this dr. Same guy told me i should stop taking whey protien pshhh..
