bladder infection
"I was prescribed Macrobid for a UTI. Within 12 hours of my first dose, I had extreme body and muscle pain from my ankles to my shoulders.  I am 100% aware that many people can take Macrobid and be fine, I'm just relieved to read that some other people went through what I did for the simple fact that I thought I was dying! The morning after I started taking the meds, even my lungs felt bruised. I was too weak to hardly even walk. I returned to the doctor and totally thought they would hospitalize me. He wrote me a new script and sent me home. My mother and husband took turns taking care of me until I stopped vomiting and writhing in pain, which in total took days. I couldn't eat and even couldn't take care of my small children for two days."
