Yes, this is really my area of pain. The nexus of most of it seems to be at CL5F, then radiating down into thigh and out to trochanter-area. Back in late September, the CL5F pain finally seemed to be gone and I thought I was home free. Then, in early October it came back, and has gotten worse and worse since then. My surgeon's PA put me on prednisone tablets today to try to counteract inflammation. Blood work shows no infection, and the x-ray today showed no change (which suggests no loosening, right?). They also want to do an MRI of the low back, which is fine, but I know the CL5F pain has its origin there, not in my back. I asked about iliopsoas burisitis, but only got kind of a condescending "maybe but not likely" from the PA.
Goodness me, I don't remember what all the exercises were per se that PT did with me back in the Summer. I do remember the PT literally laying on top of me, spreading my leg out as wide as he could to stretch my adductors or something like that - I wanted to curl up in the fetal position after that session, it was so brutal.
