I've left them alone so far! ...aaaand, so far, two of them are basically gone, two of them look like shriveled up prune, and one of them I accidentally popped... dancing... It's freaking weird man. I mean... what is that in there, some water, or sweat or.... or what man... xD
ahh, some of these stories freak me out. i've never had anything beside water blister which i get on like a daily basis.
it's never freaked me out though, and i've never gotten an infection from popping them either. :/
