urinary tract infection
"I took Nitrofurantoin for 2 days and had to stop. The dosage was meant to be for a week.

I developed a fever, tight sore throat, dry cough, difficulty swallowing,

extreme fatigue, nausea, dizziness.

I also had neck pain, my skin felt sore when touched.

These symptoms are continuing 5 days after I stopped 

taking the medication.  Never again!"
