I have diabetes, fibromyalgia, reflex sympatric dystrophy, bursitis, arthritis, degenatrive disc disease in my lower spine, a torn menus ligament in my left knee, chronic fatigue syndrome, sleep problems and these are just the major parts of my health problems. I am on disability. Why is it that one hour I can walk, think and do all I need to and the next hour I can barely move or make a decision or think straight. No pain medication helps for long, I have been to pain clinics, PT, several specialist and no one can tell me anything but the name of the problem, where am I headed health wise?
