Is it normal that i put a plus sign on a mosquito bite with my fingernails?

AH I do the exact same thing! You dig in hard, then go the other way, like a cross!
It takes the itch away, if you push really hard.

Somehow I feel less alone...

I do that first, then, itch until it bleeds..Feels great.

I have always done it. My mother taught me to do it.

I do this also
