I am guessing that this is all allergy-induced/related since they found no lung or heart damage. I am also on
Prevacid for acid since I have a history of gastrointestinal problems (had acid reflux several years ago, and it seemed to go away with Prevpack), but for the past couple of months, I've had stomach burning, and at base of rib cage and between breast bone, for which I've been taking the Prevacid for almost a month now and watching out for caffeine, tomato sauce, etc.
