No, this does not sound like typical symptoms of someone with new herpes (new because your last test was negative for both types). I would recommend that you stop taking Valtrex at this time. You could be masking symptoms, and could be alterating results of any antibody testing you might do in the near future. If you break out with significant water blisters or symptoms that are remarkable, go back in and let your doctor have a look. To me, your symptoms sound like chapped lips, but again, very difficult to say over the internet from your description.

I forgot to note that my doctor has tried several creams as well as oral antibiotics over the past 5 weeks (to no avail).
