Since you felt better when you added two medications (Tindamax and hydrocortisone) it could be very useful to figure out which of the two was helping you - it's possible but unlikely that you need both. Why not try the Tindamax again to see if that alone does the trick? If not then budesonide enemas might be preferable to hydrocortisone, since there is less systemic absorption.
A small amount of pouch inflammation is very common, so it's hard to know if yours needs to be treated (if that's not the source of your symptoms). Also, Flagyl is a more common first line antibiotic choice, but since Tindamax may have helped I'd stick with that during the experimentation process.
Good luck!
