I can't believe what I am reading! I have been a competitive run...

I can't believe what I am reading! I have been a competitive runner for over 25 years, and in the past two years I started running mainly trail ultras - races up to 70 miles. This March my husband noticed a huge dent in my left glute muscle that over the course of four races got worse and led to a secondary dent in my hip area. I just assumed I had injured my muscle somehow, but no amount of rest, PT, or stretching has helped.(it's been 6 months now) I developed hip bursitis, medium to severe pain in all my joints, including both knees, my left ankle, and extreme spinal stiffness. None of the experienced PTs I've been to have seen anything like my dent, and they are baffled by my worsening condition. I'm so scared I'll have to give up running altogether, as my joints are failing me. My PT has advised me to go to my regular doctor to get bloodwork, X-rays, an MRI & all tests done to see if something is wrong with me that is beyond muscle-skeletal. Before all of this, I had low back issues but no joint issues at all. I found this web site by chance, and suddenly I remembered that several months before noticing the dent, I received 2 steroid injections in my butt, as well as pills & cream for a super severe case of poison oak that covered my whole body and face. Do you think my doctor will tell me if it was Kenalog if I ask? I, too, am very very interested in any other stories of severe joint pain and inability to run especially after receiving these shots. I hope we can help each other figure this out & get answers.
