For four days, I ve had tiny clear bumps over my top and bottom lips. They are very dry, rough, and peel frequently. The taste is similar to when I had poison ivy in my mouth. I dont have a rash anywhere else and it does not itch. Today it seems like I may have some bumps on the roof of my mouth. The only irregular things I ve done lately are: Use a shampoo sample I found under my sink Eat mangos, which I ve never had before Eat Wasabi Ginger chips And consume more Apple cider vinegar and cranberry juice than usual I ve never had a cold sore before, and have not shared anything with anyone in a way that I feel could pass on the virus.
