Pain Relief

Hello all. I'm newly registered as my adult daughter has recently been diagnosed as being on the Autistic Spectrum. She has suffered severe pain throughout her body for about 4 years and after being prescribed various drugs (with their inherent side effects) that provided no relief, found that medical professionals seemed to dismiss it as psychosomatic. Having been told that people with Autism can feel pain differently from NTs, we are hoping for a renewed approach from them. Has pain like this affected anyone here? We'd be interested in your coping strategies and whether you were able to get relief in some way.
