So, why are you even waiting? You should probably just head to the doctor already. I mean, honestly, without an MRI, I don't think you or your physician are going to get any real answers. Once you get that sorted, you can deal with whatever else needs doing. Recovery periods tend to be pretty long, so maybe prepare yourself for that and just hope for the best. My knees used to act up too, though I'm not exactly an athlete or anything, and then I'd go play some casual pickup soccer, make one wrong move, and—boom—torn ligament. Anyway, I'm currently exactly three weeks out from my own surgery.☕
