Playing tennis in late October of this year, I pulled what I thought was my groin muscle during a tennis match. I took time off and after several doctor visits, got an MRI and the results showed that I have Piriformis Syndrome along with SI Joint Arthritis. They took my blood to rule out Ankylosing Spondylitis and I have to wait to hear the results. Anyways, for the past two months because of this I have taken off all forms of cardio and weight lifting per the doctor. It finally started to feel a little better before I got my MRI, then after I got my MRI results they wanted me to started stretching it some at home. They haven't said Physical Therapy yet so I did some stretching at home and it just seemed to flare it back up all over again after I seemingly was making progress not doing anything. Just wondering if anyone else has been through this and what I should do. Should I just go right to Physical Therapy even though the doctor hasn't said to do it yet and wouldn't all this stretching just make it worse again? Also, he put me on a Medrol Pak (steroid) of 4 MG for this past week and it seemingly did nothing. Ugh...so frustrating.
