sinusitis
"I took Augmentin starting last week for a sinus infection. The first few days were fine, and I felt relief from the pressure of the infection. However, by day 5, my stomach hurt so badly, and around my body to the back. I could not eat. My stomach was rock hard and I felt so bloated. I could only suffer through day 8. I had to stop. I cannot tolerate this medication, and will never take it again."
