question: A dentist decided that I need a root canal, and asked me to take Amoxicillin before the procedure. On the 4th day (last night) after I started medicine, about 10 minutes after I took the required does, I developed a rash and itchy feet. I put cortisone on the affected area and felt better and went to bed. After one night sleep I still feel that the rash area are itchy. Should I stop taking the medicine or should I continue? Thank you for your expertise!
