Hi George - my major problems are different (POEMS Syndrome plus a bunch of other things. See my website for details: http://poemssyndrome.info/ I have been to thte Mayo Clinic three times becasue there is an expert there that specializes in POEMS. Nearly a year ago I did have a heart problem and ended up with open heart surgery. I had a double by-pass, two values repaired and a pacemaker. All is well now but , wow was it a tough surgery. I never expected a heart problem because I have normal blood pressure, low cholesterol, not over weight (maybe under weight), not a high stress life,I don't drink and I don't even swear that much! But I did have a problem and all seems well with that issue now. If you are being treated at the Mayo, you are at the best place and hopefully they will solve your problem. There isn't much that they can't solve. How did you locate me? Anything else I can answer, I would be glad to.
