my 89 year old father had a pace maker put in over a year ago. just after his feet began to swell and parts of his body developed a rash: hands, feet, back, well pretty much every where, though not all at once. He's been seeing a dermatologist for about 11 month. symptoms improve while on prednisone. the Dr's suspect an allergic reaction to some of his medication, though after almost a year of treatment and tests, they still don't know why he has this. I saw a picture of a goat sufferer and thought his rash looked remarkably similar. I want him to enjoy his final years and am tired of the lack of answers as no one seems to be in a hurry to fix this. Suggestions?
