Ann, I hope that all the treatments eases your pain...you have enough to deal with, added that your extra hours must make you stressed a bit, which I know for me makes me tighten up.
In PT this last go-round, the therapist noticed my hip didn't move right and I compensated...her exercises have helped a lot. I fell many years ago and didn't go to the doctor, which probably damaged my SI joint, causing the gait problem.

The extra problem with this type of pain, for me at least, is that pain meds don't usually help. I seem to remember that gabapentin helped a bit, but not many people can tolerate it.

Anyway, prayers sent to you for relief
