SMZ-TMP DS and sinus infection

I was prescribed this as an inexpensive option to treat a long-term sinus infection in March 2008. I had no prior history of allergic reactions or prior health problems. After 3 days (6 doses) my whole body was in throbbing pain, I felt like my skin was on fire, and I was seeing spots, and had difficulty breathing. I initially had NO RASH or visible/external signs while taking the medication. I immediately stopped taking the medication and saw my doctor, but symptoms persisted for a week. My doctor prescribed prednisone, and had to up the dosage two weeks later when a rash formed over my torso and legs and persisted for 2 months.

I've started taking this medication for a week now for a bad case of sinus infection. Its so bad the doctors say it is backed up in my head and isn't draining.My eyes get really red, migraines and headaches causes really bad pressure in head and I also have fluid in my ears. I guess this is why it was prescribed to me. I woke up one morning and my face was all swollen on the left side of my face and my lymph nodes in the back of my neck are all swollen for about 3 days now(looks like lumps in the neck). Anyway, I decided to leave the house for one day since I started taking this SMZ-TMP DS, I ended up catching hives throughout my body and got tingling every day after that. I read the bottle and it says Do Not be EXPOSED to excessive exposure to direct and/or artificial sunlight and it was quite sunny that day. I don't know if my meds are working but I think I will be seeing another Dr. to change to another medication.

vaginal itching. should I stop taking it. It is for a sinus infection
