My husband has been in the emergency room three times now with the following symptoms: severe abdominal pain, bloating (no gas), excessive sweating, and vomiting. He has a history of heart problems. The hospitals do an EKG and send him home. The first attack was 18 mos ago and was followed by an attack a year later. The next attack was a few months later. These are infrequent, but very scary--and expensive. Both his blood pressure and heart rate drop during these attacks. We can't associate the attacks with any food. Two attacks came several hours after breakfast and the other at the end of a light meal. We eat very healthy with no fatty meals whatsoever. The nurses indicated that gallbladder inflammation was a possibility. Someone else suggested a drug interaction?? Any suggestions?
