bacterial infection
"I took this medication because I have an ear infection and a swollen gland that's causing a sore throat. These pills are HUGE. I took two pills yesterday 12 hours apart and went to bed at 8 PM. I woke up 3 hours later and started vomiting... A lot. After I had calmed down a bit I went to lay down... And I had to run back to the bathroom to vomit again. I kept feeling sick but I had nothing left and the second time there was blood. Not worth it at all."
