urinary tract infection
"I've taken a lot of antibiotics in my life, and I've never had a bad reaction. I took ONE dose to treat a UTI and had extreme joint pain (mostly knees), dizziness, ear-ringing, etc. Thought I was crazy till I googled it and found it this isn't uncommon. A day later I still feel horrible - spaced out, weak legs, etc. DO NOT TAKE THIS and tell your friends and family"
