I need some help please.

Briana 💕☺️✨ • 24 years old🥰 Engaged to my best friend, Momma to a 2 year old boy & 7 year old pit bull.💜
I just need help figuring out what kind of bites these are, they are only on my feet and legs! I can't figure it out. They don't itch unless my pants or shoes rub up against them. Sorry it might be a tmi to some people, ignore my nasty looking feet!
Thank you in advance.
