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.
