I honestly do not know. I have never heard of nasal herpes. I would call your doctor and tell him/her that you found them in your nose also and ask what you should use to treat them.

I went to the doctor and was prescribed valtrex. I have to take it twice a day for 10 days

Nasal Herpes totally sucks! I have it right now along with a bad cold. It's in both of my nostrils and hurts so bad just to blow my nose. And being inside a muscous membrane like the nostrils it takes forever to get rid of. It seems like now every time I get a cold, I get these too. I've been taking Acyclovir 200 mg/3 times a day and try not to blow my nose (which is very hard) so the insides can dry up. I haven't even gotten a cold sore on my lip in years, now it's just in my nose. Good luck

Oh yea, and make sure to take 1200 mg of Lysine and 2000 mg of Vitamin C a day. It will help in the healing process. I'm going to keep taking the Lysine to prevent future breakouts if it helps.
