My knuckle and fingertip swelled
up, turned red, and was warm about 2.5 wks ago, just sore on the inner knuckle, could not find any insect bites, no injury, no hang nail. Swelling went down after several days, then it came back with a vengence with severe swelling and lots of pain but this time only in the fingertip. The pressure was so intense that I tried to drain it, I know I shouldn't have. Nothing would come out.
