I have suffered with I. B.S. D. for many years along with anxiety and depression. My IBS has been severe for weeks now. I now constantly have stringy poo & it's such a small amount each time unless it's full blown diarrhoea. Iv,e now convinced myself it's cancer. I have seen a doctor who a few weeks ago did a fit test to check for blood in my poo which came back clear. She also examined my back passage which was clear. I'm now no pooing much at all & it has mucus in it. She thinks it's nothing to worry about. But I,m not convinced. My life is on hold & my whole day I'm in a state of panic.
