Sulfamethoxazole-Trimethoprim DS and third day

I was prescribed sulfamethoxazole-TMP as a second round of antibiotics to kill off a persistent sinus infection. For the first couple of days I felt fine, but then by the 3rd day out of 10 I had a persistent headache in the evenings. This lasted two days and then went away. Then on the 8th day I woke up with a rash all over my body of small red bumps, which looked like tiny mosquito bites. They don't itch, but I can definitely feel them rubbing up against my clothing. I had some red wine last night, so the extra sulfur in my body might have pushed me over the edge... Also, I feel light-headed and tired. I called the advice nurse and she said just to drink a lot of fluids to flush it out of my body and to take another round of the antibiotic to see if it gets worse! No way, lady! I think I'll stay away from it, thank you very much. My sinus infection is gone enough. I have never had a reaction to any medications before, so this really surprised me.

i was given this for a sinus infection. the first day i had red bumps all over my legs. i have really bad allergies so i passed it off. the second day i had the bumps, felt a little disoriented and dizzy, and i felt pain in all my joints. by the third day i had a fever of 104 degrees, all the other symptoms and all i wanted to do was sleep. my fiance gave me Advil and it brought my fever down to 102 but then went back up to 103. he took the prescription away from me. he got worried and took me to urgent care where after waiting 5 hours to see someone they said i had the flu-drink lots and sleep. oh and maybe its a reaction to the medication. my temperature went down to normal day after i stopped taking it, my joints and swelling are better, i still have the bumps on my legs but i have another appointment with my regular doctor later this morning so i'll see what he says. my brother called earlier today and as soon as i told him the name of the medication he said "oh, so you have spots all over?" so i guess it's not just me?
