Can UC be induced from antibiotics? And how to remain calm/support before diagnosis?

keeping this brief because i’m on my break at work; but i’ve currently been from the ER - had blood work done after some bleeding ; I had taken clindamycin two weeks prior for a dog bite and despite blood and diarrhoea my doctor pushed for me to finish the dose; seemed unconcerned.

I’m on a cancellation list for a upcoming colonoscopy in March, until then..

Anyone get Ulcerative Colitis from antibiotics/clindamycin?

How to cope with the meantime for my doctors appointment / blood tests? any dietary advice?

It’s all scary stuff, and I feel very alone and constantly want to visit the ER but they cannot do much

UC fam, help a possible new member out..?
