Sulfamethoxazole-Trimethoprim DS and tmp

Hello, I took two pills of Sulfamethoxazole-TMP d's the first tablet caused no noticeable side effects. Unfortunately the second caused a severe headache as pressure built up behind my eyes. I haven't had a headache in years, without being sick. The headaches were pulsing at times and worsened should I bend over or exert my self. I became fatigued easily early in the day, and I work out a lot and try to become fatigued purposely almost everyday. Immediately after taking the second pill I felt sharp pains in my stomach. I haven't had an upset stomach in years. The effects of the second pill did not stop there I also had started feeling the aches in my joints. My skin itches where I usually rub against things. Such as ankle to ankle, knees from wrestling and back from laying in bed. I also got three blister bumps one on my back and two on my face. It reminds me of what I get when I eat fast, canned or preservative packed foods. The prescription was due to a minor skin infection which is healing just fine to the best of my knowledge despite discontinuing the Sulfamethoxazole. Oh and the scariest and strangest side effect that I have not heard of yet is, my eyes became bloodshot after the second pill. I mean it looked like the whites of my eyes were blood. It has finally passed and my eyes are returning to white after three days from taking that second pill. I thought they were never going to go back to normal. The last side effect was blood in my stool. Scary. I will never take this stuff again. I just hope I get back to normal soon. Going on fourth day trying to rest and get better.

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.
