The doctor I saw on Wednesday thinks my problem is piriformis syndrome. I have piriformis tendinitis, high hamstring tendinopathy, sciatica, and some hip bursitis. AND, he told me something new. After explaining everything to him and him examining me, my movement, flexibility, what hurts when... (the two other doctors barely touched me--very poor examination)... he said that they are seeing people who have had hip arthroscopic surgery (like me) who develop this piriformis syndrome; people who haven't been rehabbed correctly after surgery.
Soooo, he prescribed aggressive PT for the next eight weeks, AND I am seeing a PT who is a runner who treats runners. YAY! I have hope!! And, it makes sense... I have been able to run just fine for miles and miles with not too much trouble or pain, and then not be able to run at all for four or five days--too much pain.
Anyway, I go tomorrow to my first PT session, so I will let you know!
