Sulfamethoxazole and leg cramps

I just finished my 10 day cycle of sulfameth/trimeth for a sever sinus infection - I have barely been able to eat the whole time - forcing myself to when I started to feel too weak - i love food and it has not appealed to me. I have felt nauseus and like there was a granite slab sitting in thepit of my stomach. I have also been extrmeely moody - just thought that was from lack of eating. Definitely dehydrated. Been getting leg cramps the whole time and one day I couldn't touch the skin on my right calf - i thought I had caused nerve damage from a short jog on the beach, but it was gone the next day. Then, lo and behold, on today, the last day, the nausea is still there, I feel tired and my back is really sore and I am covered head to toe in a really ugly rash. SOund familiar? I was told that there were no side effects to this drug except for dehydration. THis is first first time I have taken antibiotics in 10 years and I am not happy with the decision, but was so desparate.

i recently got a leg infection and was given sulfameth by my doctor,i am getting strong leg cramps, muscle spasms,i got hot very easy like i was going to faint, when i was outside and it was 80 it felt like 105 . i got dizzy alot, i would never take this again.. thankyou

The discomfort of my bladder was gone after one day but I have experienced very painful and contentious leg cramps all night for three nights since taking sulfameth/trimethprim 800/160 tabs . (Sept.9 06)

After two days I developed a rash on the back of one leg and I had severe leg cramps in the middle of the night.

after 3 days started itching ,shoulders neck then stomachand arms and have had leg cramps in the middle of the night, but it works. This is the first time I have ever had any after effects
