urinary tract infection
"I've just finished my treatment for a urinary tract infection.  I no longer have any symptoms from the infection.  First 8 days of a 15 day treatment was fine with no side effects.  Beginning the 9th day, I began experiencing a mild rash and itching which seem to begin on my chest and neck and migrated to my back.  A bit of a nuisance but tolerable.  Around the 11th day, I began to experience mild joint and muscle ache and a tender scalp around the base of the skull.  Acetaminophen and ibuprofen have helped to overcome this but by the 14th and 15th day, I felt like a had the flu with no nausea but a loss of appetite.  I took the last pill this morning and by 1PM, had to lay down with chills, aches and pains, headache and a slight fever."
