I am a 51-year-old male who was diagnosed with Osgood Schlatters disease in my youth. Then, in my young adulthood, I was diagnosed with osteoarthritis in both knees, which later progressed to both hips due to my gait, weight, and activities. Currently I have been experiencing a cramp in my extreme lower leg near my ankle on the side of each leg in what feels like the bone. The cramps are so severe that the only relief is to rub each leg bone where the cramp is with my forefinger and thumb as hard as I can. What could possibly be causing this pain? I've never had it before.
