I had a tough training tonight (middle distance runner), 200 400 600 800 600 400 200. I only just noticed a sharp pain in my knee when I bend it or run with it? I'm pretty sure I had this pain a few years back in 2014. In 2013 I had osgood Schlatters but it isn't in the same location. It's like inner knee towards the inside in that little gap? Right now I also have full Achilles and shin pain in both legs. As well as hip pain in and off for the last few years. I've had MRIs and X-rays on both knees and hips in the past.
