38 yr old female, no other health issues. History of fissures and piles. Take 1/2 dose of miralax and 3 tabs of magnesium complex daily to keep stool soft. Typically with this I don't experience any symptoms. Every so often (2x/month) I experience an acidic or sour smelling stool for 1-2 days and i experience a fissure flare-up. I have kept things under control, but wondering if my bacteria levels could be off causing this occasional stool problem. Would a probiotic help? Should I take anything else? Thank you.
