Thermometer symptoms and conditions

Oh my God, a few days ago i went to ER at 3:30 in the morning cause i felt like i was gonna die and my leg hurt. of course they didn't care to check my leg, but they said i have UTI so i am on Bactrim right now. the first two days were fine, but now i feel as if i'm gonna die seriously. I feel like i have high fever (i don't have a thermometer) my eyes feel as if they're gonna burst out of my skull and my throwt is dry and just dry. my body is ackeing and i feel dizzy. Does anyone know if you can die from bactrim>? should i finish taking the doses given to me to take the UTI away? what do i do? my husband is already frustrated with my ackying but i seriously feel pain. any advice?

Symptoms which were not in existence prior to staring on warfarin although my doctors say they don't think it's warfarin I'm sure it is. I usually need to take around 9.5 to 10mg but my INR is never stable.
Side effects are extreme fatigue, fuzzy thinking, forgetfulness, hot rosy cheeks.
