I had been trying to get the VA doc for a few years to figure it all out. I was very active with exercise up until about 5 years ago and then it seemed like my body gave up. I went from running 3 miles 3 times a week to no able to run to the end of my street. Ankles, knees and muscle in lower extremities ache. Many days i feel like I had been to the gym doing squats for the first time after a few days. Even hurts to the touch. Doc cant find anything.
