Hi Doctor, I have a continuious pain in the same spot just between my shoulder blades, my doc has done blood tests, xrays and had me on anti inflammatories, these have not worked, he says I have a mechanical back, I am 50 years old, he says I have artheritis, I have had numerous beds, thinking it was the mattress, I have sleepless nights tossing and turning,am always tired, is there anything else I can do to alleviate this pain, thank you
