I don’t have your daughter’s diagnosis but I do have chronic pain, diagnosed as ‘Central Pain Syndrom ’ following a midline stroke. I too had intense burning, knife like pain all over my body. At first, I just remember the intense burning, like coals being pressed into my body. It was awful. 6 years later, Acupuncture helped a whole lot. Did not cure the pain, but diminished it to a level where with Opiod and neurotrophic drugs ( to interrupt the pain signals.to my brain) I can function and am able to do activities of daily living and get out, drive, etc. it does, however, continue to be a daily battle. Good luck to your daughter.
