@Elif, if the difficulty worsens, I will find out about the enemas. I have used some before--I think mostly before surgery, but I got pretty comfortable with them.
Currently, I am able to empty. I just have to be really careful not to strain, which often means multiple trips for one BM. The issue is moreso just that, for me, difficulty emptying and only being able to pass gas in one position usually indicates inflammation or some sort of problem.
Hopefully this is something I caused with the mushrooms/straining...and it goes away without invasive treatments. Just not really sure how things will go right now.
Thank you for the advice though! (and everyone else on here; it has been very helpful.)
