I have excruciating attacks in my chest. My heart checks o'kay. No Dr. seems to know what is causing this pain off and on for ten years or so. They say just unknown chest pain. I have learned to bend forward and it helps to relieve the pain. I know the pain is similiar to heart attack. I have been diagnosed with Fibromalyia and going for tests to see if I have Lupus also. My muscles hurt all over, am so fatigued most of the time, have chills and inward fever off and on etc.If there is anyone that has had the Dressler's Syndrome related to autoimmune disease please reply to me.
