I have an odd injury that’s been hanging around a couple months. I suspect perineal tendinitis because pain is back of ankle and also where tendon attaches on outside of foot. I can run on it with little to no pain, and that’s not changing. But every night I wake up with pretty severe pain that lasts a short period, then disappears. I worry about potential fibula six, but again, i have run pain free without it getting worse for some time. Thoughts?
