Had first cold sore in april , went away in may. 3 months later in sept had another , it healed after anti virals and just a week in between and another one next to scar of old one. why so frequent? is it possible? took valtrex again, feeling upset?

Recurrent outbreaks often are especially common in the first few weeks or months after a new HSV infection. Most likely this will settle down; most oral herpes recurs no more often than once or twice a year. If an outbreak was not tested to confirm virus type -- usually HSV1 for oral herpes -- do it now. If your infection is caused by HSV2, outbreaks might be more frequent. Good luck.
