Could be a really bad sunburn, the image isn’t super clear. Google “sunburn blisters”
It’s called sweat dude.
That’s sunburn. Should have worn more sunscreen.
It will go away in a few days.
If not sweat or sunburn, then maybe you’re not accustomed to the humidity wherever you’re at.
Yeah, looks like it could be the start of heat rash. @turnerpike20@lemmy.ml do you feel a sort of prickly heat under the bumps?
Could be you might have come in contact with a poisonous plant like poison ivy, poison oak, sumac. An abrasion from a seat belt, back pack or something could cause some skin infection or folliculitis. Germs are already on the skin and then it gets some kind of point of entry. Ant bites, or mites might also lead to some infection. Shingles is more like clusters of cold sores, but it could be a virus.
Because it’s 100f in Chicago.
