Tonsillitis/Pharyngitis
"Went to the doctor for fever, severe dizziness, and some sinus drainage and sore throat. My flu swab came back negative, so she labeled it as acute pharyngitis, prescribed 5 day Z pak. Less than 2 hours after my first dose, I had horrible, painful diarrhea. I also began to experience severe stomach pain even though I made sure to take it with plenty of food. My symptoms did not improve,  and I began having headaches as well. It is now the day after my final dose, and my sore throat is back, my fever is still high,  head hurts, and I&#039;m dizzy as ever though my stomach is finally feeling better now that I&#039;m out of this useless medicine."
