I'm a fourteen year old girl, and I now have a bunch of zits that WERE NOT THERE YESTERDAY on the underside of my arm. I squeezed them and pus came out, but now they look 10 times larger and hurt.
I have no idea what's causing them. They're on both of my arms.
Could it be my new body wash? That's what I suspect, but I use the wash all over my body but the only place I got the zits were on my arms.

Ahhh! Help me please!
