Does anybody else suffer with back pain who has an MPN? For weeks I have had excruating back and hip pain. I have 120mg of morphine a day plus paracetamol and pregablin but all of that isn't touching the pain. I am looking terribly pale but I am putting it all down to how miserable I am feeling. I have been wondering if the scarring of the bone marrow that is associated with this disease could contribute to the pain? Anybody with any advice?
