Question for those with diagnosed SPD

My Drs think I may have SPD and are sending me to physical therapy next week.

I was wondering what others had experienced, and if there was anything I can do in the meantime to help with symptoms. Also, has anyone else gone to PT for this and had symptom relief?

I have difficulty walking, climbing stairs is nearly impossible, and I cry at night trying to find a position which doesn't hurt, especially when I turn. I don't know if this is TMI, but it hurts mainly in the crease between my thigh and crotch, and in my inner thigh, and sort of radiates back towards my butt and over to the other side. They said it's a sort of unusual place for the main source of pain but my other symptoms sound like SPD.

Any advice while I await PT?
