I don't think a doctor would tell you to wait a few days to make sure. The best and only med I ever used that made bleeding stop/decrease was mesalamine enema. Have you ever used them?
Besides enemas there are also suppositories like Canasa but they didn't do much for me. Others here have also been prescribed steroid enemas but I never used them so cannnot comment on them.
It's a way to get to the bleeding area directly because oral meds rarely get their medicine delivered that low in the colon.
I know about
denial
tried it and it doesn't work lol.
