Sinusitis
"I was just prescribed amoxicillin clav 875mg- 2 pills a day. I&#039;m going on my 3rd day of meds. The first day I had a horrible headache but I&#039;m prone to them and the weather was rainy too. Soo I figure that could have been something else. The worst thing I have experienced is the nausea. It happens a few hours after I have taken a dose. I&#039;ve been taking the meds with a half bottle of water. I sip some milk and eat cereal along with it each time. Usually a few hrs after dose and or when I eat I will have to go to the bathroom. Somewhat loose stool. May be the nausea but I also feel sick/feverish a few hours after the pill but I do not have a fever. Comes and goes."
