On long-term abx and now painless internal hemorrhoids - help

Hi,
I am several months into treatment for chronic Bartonellosis which includes abx and probiotics and these upset my stomach and cause me very lose stools.
I got some blood, got tested to rule out C-diff and doctor thought probably internal hemorroids. I realised I was straining alot from all the pressure in my bowels when I go. So I am trying not to, and that has helped, but still I am getting some blood some days.

So my question is, what steps can I take to heal the problem?

Thanks
