I had sharp pains whenever I moved my arm, especially when I extended it, very sharp pain though, made it hard to do any excercise. My arm didn't swell up for about 3 months, then he drained it and it went away. I didn't see a physician until the swelling started. but it was like new as soon as he drained it and I've been working hard on it since, no recurring anything.
I had it my elbow for awhile, it was killing my workouts and rest wasn't doing anything for me. My elbow finally swole up and I went to an urget care place where the doc drained it and I was fine pretty much right after. U got it in one knee? Any swelling yet?
