I am having pain in lower left abdomen just to the left of belly button. Also, I am constantly having gas issues where my stomach gets bloated mostly during night. The pain is constant, sometimes it goes off and sometimes the pain is more. Few months back I was diagnosed with IBS. That time the doctor had given prescribed medicines which I took and then became fine. This time the gas issue started again after having outside food and it's there. I am currently taking the same medicines since 3 days which the doctor prescribed few months back. I am now worried if I have some serious issues. Please suggest. I am attaching the prescription which doctor had prescribed.
