I have herpes simplex 1 for about 5 years. I didn't have any outbreaks after the first one for almost 2 years, and then about once a year. My doctor prescribed Valtrex to take when I have outbreaks. Recently I have had symptoms of what I though was a herpes outbreak (I just have tingling and light itching/doscomfort-I have never had an actual sore since the first outbreak) and took my the recommended dose 1000mg twice a day for 7 days. The symptoms did not go away, so I continued taking them for a total of 3 weeks. I still have tingling and slight itching. Is this a herpes outbreak or could it be something else? Is there any reason if it is herpes why the valtrex isn't working?
