Chronic pain in bones and joints

Patient: I have chronic pain all over my body. Mostley in my bones and joints. I have been to MANY different doctors. They don’t really seem to care enough to find the cause they just keep giving different meds to try. Nothing helps. Heat makes it worse. I have tried rest, exercise, ibuprophine, naproxin, flexarel, diclofenac, pprednisone.nabumetone and more. Any ideas what could be causing all this pain?
