I recently suspected a herpes infection coming on, even though I am not diagnosed (waiting for blood tests to come back). I felt tingling on my lips and also had redness down below. My doctor prescribed me valtrex just in case and I started taking it because I was worried and she said it isn't harmful even if my tests turn out to be negative. Anyhow, I am taking 500mg twice a day for the possible gentile herpes, but can it also work for the possible oral herpes? Also, I am out of the country for the next few days and I couldn't get my hands on abreva, so I bought something called Urgo cold sore relief and have been using it. Do you think these are bad ideas? I just want to be safe and prevent an outbreak, especially before I go back to school and have an embarrassing cold sore on my face next week.
