Ran a ragnar last November, which is not unusual for me, and have had pain above my right butt cheek ever since, just below the iliac crest. The pain ranges from a dull soarness to a sharp sudden tingle radiating down my leg depending on my activity. It has regressed so that i only notice stiffness and pain after intense physical activity. I can get about a mile and a half run in now before I have to stop. I also notice it going downhill specifically on long hikes. It has improved but progress is extremely slow. I even went to PT, which ended up being a waist of time since they didn't find anything obviously wrong. Any thoughts? TIA
