I have the same issue. Just like the other girl said, its not from endo but more from our bodies response to the pain. I did pelvic floor physical therapy for a few months and the phyaical therapist cpuldnt believe how tense my entire body was. She helped a TON when it came to my back pain!

Yes ,yes ,yes all the above and its happening more frequently now .my shoulder ,neck and head hurt all the time.

I have noticed a lot of upperback and neck pain. I have 3 pillows that i alternate with through the night... I never related it back to endo but it makes sense... the pelvic floor therapy sounds interesting I should look into that too..

Is this just at a physical therapy office? I’ll def look into it!

I am doing pelvic floor therapy. But it involves your whole body because your nerves and your muscles get so tight that it causes other things to get tight that really have nothing to do with the Endo. It just hurts because you’re so used to constantly being hunched over that it’s affecting your posture. Look in the pelvic floor therapy it has helped me, but at the same time it hurts me. It works really well but the next day feels like a flareup but I know that I making progress
