I Was Put On Bactrim For A Infection On My

I was put on bactrim for a infection on my breast. I have to take two tablets twice a day. Now I am experiencing salty taste even while trying to eat or drink anything, burning up as if I'm setting over top of a camp fire, chills from time to time as if I'm setting in a freezer. Not sure what to do. Could I be allergic to this med? I've never taken a sulfa drug before so I'm not sure what to do.
