Bactrim and kidney infection

I'm on bactrim for a kidney infection. The first day I was fine. I was in so much pain, after 2-3 pills it made me feel a lot better, I'm taking bactrim 2x a day for 7 days. I'm on day 4 and feel like crap. My backache is back, headache, cramping, stomach ache. I feel worse then I did before the meds. I stopped it this morning, but go so sick I had to take one. They make me feel better for a moment, until everything kicks in. And I cant do this with a 5 month old to care for. I go to the doctor in 2 days....I will be stopping tonight. Thanks to everyone elses answers!!

Honestly thank you for this website! I mentally feel better if not physically yet. I was prescribed 3 day/2 dose Bactrim for a UTI. I have NEVER had a reaction to antibiotics or any type of medicine. I can no longer say that.

That said...thought I was dying. My temperature was 102 for days, every muscle in my body felt so sore I felt like a car had hit me and then hit me again, ridiculous size headache, massive stomach pain, insomnia, thought I would faint every time I stood up, could barely walk, no appetite, etc. It was ridiculous and I thought I was going crazy because how can one medicine do all that?? I now have a whole new respect for antibiotics.

Since I was feeling so horrible by the 2nd day on it I went ahead and finished the last day. (hindsight probably stupid)

This is my first day off and all my muscles are still killing me, especially my neck, chest, stomach, back. Still feel weak and my temp. this morning was 101 and went down to 100 now.

And I don't know if it was the medicine or just being sick but I've been so 'out of it' today and just depressed. I can not WAIT for this medicine to be out of my system! And I will never use it again.

To add insult to injury I'm not sure if it cured the UTI all the way. Not running to the restroom but still have slight (non-painful) tingle down there.
