I was diagnosed with Irritable Bowel Syndrome couple of months ago. The doctor prescribed some medicines and there was relief from the symptoms for a while. But now, I have severe stomach ache every day. It's a cramp-like ache accompanied with nausea. I've tried reducing food intake and stopped taking spicy/fatty foods, but there is no change. Please advise as this is very debilitating and I am unable to work or do anything productive.
