Guys me i don't know what this is, i know it's not education related but didn't know we're else to look. it might be a spider bite. i found it on my shoulder this morning.

Possibly a mosquito. If not that a spider, or a beetle. If it swells I would go to the hospital

Yea looks like a mosquito bite. 
 If it swells up or you loose feeling around that bite then its time to go to the hospital for immediate attention. 

Try not to touch it as much, and see if your body fights off whatever bit you. 
And if it is a mosquito bite, then try your hardest not to itch! It makes the situation worse. And the bite stays on your skin longer, and becomes even more irritating!
I have seen that putting deodorant on the mosquito bite really helps relief the itch :)

Good Luck! 

love, the pineapple
