I went to the doctor the other day to get a prescription for chantix , but while I was there I told them my knee has been acting up lately. My right knee is swollen, jiggly but does not hurt but it feels like there is a small ball or giant pimple ready to burst directly above my kneecap. The only time there is any pain is if I fully bend it. Then it feels like there is a strap across the top of my knee that is ready to tear. I also told them that lately once a day or every other day I have a burning sensation when I urinate so they took some blood & urine to test for gonoreah, chlamydia , lyme s disease, and gout . All tests came back negative. This knee thing came about 3-4 weeks ago out of now where. No sports injury or any other kind of injury just appeared. I guess I first noticed it when I was on a road trip over a month ago my legs constantly felt like they were about to cramp but never did. Now only my right calf gets that feeling ONLY sometimes. I can run on it, bend it, stand on it, walk on it, all with no pain just pressure.
