Hello. I have recurrent cold sores and have a Famvir prescription for this. Two weeks ago, I felt and saw redness, lumpiness and then a whitish sore that I associate with cold sores and hurriedly bolted down 1500mg of Famvir. But the sore/lesion seems to have been on the inside of my lip (the moist inner mouth), and not on my skin. Stupidly I didn't think of this til later. I think, in my panic, I just went for the meds as the easy solution without thinking. Upon reflection, I think it may have been a canker sore, not a cold sore, and my understanding is that cold sores aren't common inside the mouth. In any case, it went away within 12 hours, and now it's like a clear dark dot, as if I had a pencil jab there. It's been this way for most of the intervening two weeks, with no pain, itching, nothing. I'm posting because I'm still wondering what it was. If it was a canker sore, why did it react to the Famvir? Does Famvir still have an effect on canker sores then, as well as cold sores? Am I contagious? Was I ever contagious? And can I actually kiss my husband again?
Thanks for any advice! Much appreciated.
