urinary tract infection
"I have bad side effects from all antibiotics, which is why I ended up with a long-standing urinary tract infection. I was given Bactrim DS by my doctor. I was really afraid to take this medications, so I cut a pill in half. I also took 1/4 of a Phenergan to help with possible nausea. I was fine all day. No side effects at all until about 4 hours in. Then I developed extreme body aches, especially stiff neck and a low grade fever (which lasted 3 days). I didn't take another one, checked my urine with a dipstick and it was clear. Unfortunately the urinary tract infection came back the next day because I didn't take enough. I tried 1/4 of a pill and had the same side effects 4 hours later. No more of those for me. Going back to the doctor for something else."
