Sulfamethoxazole-Trimethoprim and nausea

After, being given medicine for a procedure I had last week. I started to get nausea and headaches. The meds where to be taken for 30 days. I had told the people at the surgical care that I had a sensitive stomach. But I guess they did not listened I rather have an infection instead of taking this. My bones ache and stopped take meds 2 days ago and still feel bad. I had cold chills and feel hot the next and spent the whole day throwing up until 3pm and now I feel exhausted and a little down. I will never ever take this meds again. This meds so many side affects they should have an alternative drug to take.

for everyone who developed a rash, how long did it take to go away? i was on sulfa for three days and now i have little red bumps that kind of look like small pimples all over my ankles and feet and my arms and hands...is this a normal side effect? i am so freaked out that it will be permanent...i stopped taking the meds.

also, i had such bad nausea i couldn't move and could not eat anything

I have experienced nausea with this medicine and I don't know if its normal but my teeth are aching extremely bad, they feel really sensitive. I know antibiotics are bad for your teeth, but I don't know if that's the cause. I have also experienced headaches and slight itching, but no rash thank God!
