urinary tract infection
"Started taking this medication this morning with the only UTI related side effect being fever and fatigue. Now since taking two doses of Nitrofurantoin, I have excruciating shoulder and neck pain. In case a UTI wasn't uncomfortable enough by itself, now as much as I want to sleep, I can't even lay down without constant muscle pain. I will be contacting my primary care doctor in the morning to send in another prescription because this is unbearable."
