In the last 2 weeks i have noticed i have these bumps all over the back on my neck, goes all the way behind my ears and the top of my forehead..

They are also all over my chest and between my cleavage.

Theyre not sore but are a bit itchy..

I asked DP to look at the ones on my neck as they are bigger than the rest and he said he can't see anything can feel them..

What are they???
