What do you think this is?

Hey,

A little while ago I started noticing on my upper arm, little tiny ‘pimple’ with white liquid in it. It was itching and if I did itch it transformed my skin into A different dry texture, almost like eczema but it’s not eczema. Then a few months later it started on my face but worst. Its like at random times in the day my face would itch like crazy. Then when I look in the mirror there would be many all over the place. I try hard not to touch because when I scratch it it transformes into driy skin like a circle patch that is dry.

Does anyone have any idea what it could be?

I have tried exzema cream, allergies pills, washing my face with okra. But it stills there. I just want everything to go and not have it spread other places. Please help!

I have a dermatologist appointment Monday but he is very young he doesn’t seem to know what it is he made me do blood tests, tried creams and allergie pills, nothing. _’ what could it be!?
