Skywhite, it's interesting because I am having anxiety and stress and I have noticed that my fibro and arthritic pains have been much worse. So, I have certainly connected memory/stress and physical pain!
Of course, I can't say for sure if you'll leave your therapist's office with less pain, but I think when you are able to work through the stress this memory is causing, you'll have pain reduction.
I can feel that I actually tighten up my muscles when I am stressed out, plus I don't sleep well. Voila, more pain.

I hope you do feel better soon.
