Hello. Yesterday, I underwent a colonoscopy with gas and air which I still found uncomfortable. After the procedure was over I felt fine for about 3 hours then I developed chills, followed by a fever and right side abdominal pain.. I took paracetomol and went to bed for a couple of hours. The pain didn't subside and I had a very uncomfortable night with sweating and right side abdominal pain. The pain is still quite bad today, though the fever seems to have gone. Should I be worried or is this pain normal? I had one polyp removed piece-meal and one removed by cold snare, as well as a series of biopsies taken. Thanks in advance for any comments / info. George
