I know ur pain but its in my sholder during softball. You might have tendanitus which is not a bad thing. It just beacuse you start working ur knee out from cold and dont warm it up a lil first. And that causes ur tendents to over work. So try to warm then up first then work out. But ass for now ice it during the nights or when ur just sitting around and maby tylonal to decress imflation. If in a week or still and u do thease and it still hurts when working out. Then see what ur doctor has to say. Its good to be safe then sorry. Hope I helped.
