What are these?

So the past couple weeks I’ve gotten bug bites on my arms, usually just one or two together. But today when I got home i had about 6 on my side.

They’re super hot and itch really bad and I am at a loss for where they’re coming from. I’m the only one getting bit out of my boyfriend and three cats. We don’t have bed bugs I’ve checked multiple times. It’s not mosquito season and I’ve washed and vacuumed EVERYTHING. It’s getting annoying because it’s getting worse and they’re uncomfortable. Has anyone seen anything like this or had it before?
