Ray said positive things about lidocaine for bleeding colitis. You might research on that for a bit.

@laoa Hi, yes thank you, I'm aware of lidocaine, but the sources i've found so far feel a bit sketchy (if you have a trusted source, please share), so I think I'll try other options first. I've seen people have success with niacin, apple pectin, and xylitol (all of these should mainly work by increasing butyrate production in the gut).

Also, acute gastrointestinal problems and fever could also be an allergic reaction to augmentin.

Yes, but I think "allergy" is just an umbrella term for the things mainstream medicine is clueless about. Like in this case it could be that my intestinal permeability was already really bad in the first place and the Augmentin killing the bacteria in the gut and them releasing their endotoxin was the final straw, or something along those lines
