I recently got switched to Imran. I have been experiencing a lot of constipation, heart palpation, chest hurting. I recently had two deaths in my family so granted I do understand it can be stress. I went to the E.R two days in a row. One for chest pains and the other for really bad abdominal pains. X-ray showed a lot of gas on my stomach and chest and inflamed pancreas. I think I am developing a digestive system problem (acid reflux, irritable bowel etc ). Does anyone else have these sort of problems?
