I am going to try to call my doctor. He prescribed amoxycillan 500 mg. three times a day for seven days. I am on the third day of pills, and in advertantly took the third dose today four hours too soon. I have started itching in my scalp and just took my blood pressure a few minutes ago - it was very high 210 over 90 - perhaps higher. I think I will call a friend to come over and take me to a clinic. YYYY@YYYY This was given to me for a dental problem. The dentist found too much calcium in my tooth. I went back and he drilled some more and was slated to return June 13. My tooth acted up and he prescribed amoxycillin.
