Hemorrhoids killing me off

Hi all, I’m in desperate need of advice for Hemorrhoids!!!

I had them during pregnancy but postpartum (11 days) they’ve become so much worse. So so painful. Issue is, I’m in urinary retention so have a catheter which means I can’t do my usual Epsom salt baths ….

Does anyone have any advice? Other then increasing fibre. I’m talking about some more immediate relief??
