I also am nauseous but only while I have the blockage. Taking 1 Coloxal tablet daily(stool softner) as it keeps bowel contents moist enough to pass the strictures. Advice from my Gastroenterologist. Before the strictures were diagnosed I had constant pain under my ribs on the right side. It felt like it was catching, but no one has ever given me an answer to this??? It's a very difficult problem to live with & yes it leaves you depressed, but maybe we that suffer really need to focus on our diet more as there is no alternative unfortunately. We are still here on Earth so let's try to enjoy...even though it's hard when unwell. Keep seeing Doctors for peace of mind also.
