Diagnosed with Post Infection IBS few months back . Started experiencing on and off pain on left side . Gastro Dr said it was the colon and all part of the ibs . Had my colonoscopy yesterday afternoon to make sure it was nothing else . Had so much pain on left side once the anaesthetic wore off . Could hardly stand up straight . Took Panadol and slept with a hot water bottle . Woke up with the same pain today . Anyone that can help ?
