My adult daughter has chronic pain throughout her body . It began in her hands , then neck and upper back , then feet , so much so that she now needs a wheelchair . The only diagnosis the doctor's could come up with is Ehlers-Danlos Syndrome . The only time she's gotten any relief at all was when she went to the ER at the hospital and they gave her a combination of ketamine , and a morphine related drug . We tried ketamine afterwards , and it didn't work . As for the morphine , can't get that outside the hospital and it's highly addictive . We would like to see what the doctor would say about methadone injections . Has anyone with chronic pain tried this and gotten any relief ?
