Hey guys, I posted here a little over 6 months ago regarding a knee injury to my left knee. It killed me while running and everywhere I read pretty much sounded like runner's knee, which needed rest and ice, etc. Well I am here now and haven't ran since then until last week and the knee still hurts, the exact same, after not hurting at all while not running for 6 months. Today I decided to try riding a bike and jumping rope, no pain, but within 1 minute of running, it started hurting.. I even jumped rope on my left leg alone and it didnt hurt.. What gives?
