I have had diverticulitis (and haemorrhoids) for years - when I get discomfort, it usually means I will need the loo within half an hour.
I found a lump in my sigmoid, which was slightly uncomfortable, so I sent off the bowel screening kit and had a colonoscopy and a polypectomy (which was clipped), four days ago.
It seems it might take a fortnight to fully recover... I do feel better... but I have avoided palpating the area - as I think it best to leave it undisturbed to heal.
The surgeon said the clip would go in a few days.
The polyp was on about 7mm diameter, but about 15mm long... but I had been water-fasting for 38 hours before the procedure, so it might have shrunk?
