A year ago develop severe pain in my calf and behind my knee where I had to stop running. Shortly thereafter (several weeks) hip and knee started cracking when walking and IT band felt super tight causing a limp. Imaging showed damaged tendons and 1/2" tear in glute. 2 x prp shot in glute and things were feeling better/healing. Started running and sever pain in calf and behind knee retuned. Hip and knee still cracking.
