Hi, sorry to hear you're flaring
![sad](/community/emoticons/sad.gif)
While I'm relatively new to UC (coming up to my 4 year anniversary - joy...), I had a lot of flares, including some that switched on full blast overnight and others that crept up gradually so that I 'accidentally' slipped from "I'll just wait and see if it calms down by itself" to severe symptoms, over a matter of several weeks or months. I never had a flare that just passed by itself, unless I count the time I had a cold with a fever where things got worse for a few days (night time BMs) then calmed down again. In all cases, I really wish I had told the hospital sooner because not telling them just meant prolonged suffering. Even "mild" symptoms can be exhausting when you have to deal with them for months at a time. The meds you are taking are quite gentle. Hopefully they will work for you but if not, something stronger could be a good option.
