Hello, I have Shingles & am on my last day of a 7 day script of Aciclovir 800mg, 5 tabs. a day. I noticed a puckering of my skin beside my mouth today, but thought it might just be because of a regular spot. It's slightly paler than my skin & seems to be a pocket of flesh, that looks kind of dimpled when I smile. I'm slightly worried as I have had a few allergic reactions in the past, but I don't know what to. My throat is feeling a little strange but I don't know if I'm just freaking myself out. I've just taken Cetrine tab. 10mg.
