I know every doesn't experience the same symptoms and this may be a stupid question, but what does a cold sore
look like? When I think of cold sore
, I think of a blister/bump that pops and then crust up. In the past my lips were really chapped, cracked corners, and then blisters formed below both corners of my mouth. I popped it, went away, but during that process it never appeared liked any of the pictures of a cold sore that I see online that's related to herpes.
