​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​I got this bump yesterday. I also have two more on the back of my thighs One on each thigh. I get these every other month or ever 3 months from sleep in my boyfriends bed.

I know it’s not bed bugs because these would be more bites and i would have them more frequently. Is this a possible allergic reaction or some other kind of bug bite ? Also they are really itchy
