flu ucerative proctitis

i have had up for 4 years now im 25 and i switched medicines about a month ago i was taking sulsalazine 500 mg 2 tabs 3 times a day and switched to canasa supposititories. when i first switched i was still taking the sulfasalazine and i had a flare up so stoped taking both medications for a week saw my doctor she wanted me to take a stool sample for parasites but i didnt take it. then i started taking the suppostitiories again and it seemed to help until now. Recently got a lot of snow here and was doing a lot of shoveling and think i got the flu. I had a 101 - 103 temp for about a week now and now my stomach seems to be all messed up again with a blood, urgency, and kinda like constipation. Im gonna stop taking the meds for a fews days and hope the whole flu thing goes away any advice

My uc is limited to the anus. I would love to take the enemas thing is i dont have insurance right now and thats why im taking canasa cause it was 100 bucks for 30 from canada pharm online. I took mesalamine 4g/60ml before and had the best results im gonna try to find that from canada at a resonable price. I just tryed to eat some white rice earlier and threw up bummer.
