I am sorry you're going through this bklyngrl. I am in a similar spot where I am on 6mp but my blood counts drop too low when I take it so I can't safely stay on it and I need to figure out the next step. In your boat, there are a few things worth considering. If you get negative results (hopefully you have a bug - funny that we think that here, isn't it?), you could try antibiotic therapy. Someone posted a very hopeful article recently about
an antibiotic combo of drugs that can help stop a flare up.
Here is a link to that:
Another thing you could try is upping the dose of 6mp as you said. if you liver enzymes get elevated, you could try adding allopurinol and lowering the dose of 6mp. I've been taking the combo for a while with good results but unfortunately my body doesn't really like 6mp and my blood counts were never high so lowering them makes them too low.
You could try alternative therapies, worms, LDN, fecal transplant, probiotics, diet... there are a lot of options but they all seem to have their own challenges. Worm therapy is expensive, LDN has low success rates, fecal transplant is most helpful is your gut is devoid of good bacteria... It is all so inidividual.
Diet doesn't seem to help or hurt me at all but some people here are able to maintaiin remission with diet alone.
Have you tried any rectal meds?
