I have been having knee problems for a while and just wonder if anyone else has had anything like this. It started as patella tendonitis in my right knee. Then one day I was long jumping and at the take off I felt a sharp pain in my patella and for a few days it hurt just to walk. Soon after I had pain in the top left part of my kneecap and also had tightness on the left side of my knee. Now the only thing that is bothering me is my patella but it isn't improving. I've been doing nothing but rehab for 2 weeks and it isn't improving. Has anyone ever had tendonitis last this long with such little activity? Any info would help! Thanks.
