Eczema, psoriasis or something else?

Anyone else have patches/sores like these?

I have recently had some dry sores pop up on different places on my body. These two pics are from my left arm and right buttock and I have another one near my groin.

I do have mild psoriasis so when the one on my arm popped up I thought maybe more psoriasis patches but these new ones are really sore 😕

I can’t get into the drs at the moment as I’m just about to go on vacation 😫 but if they keep popping up I’m going to go as soon as I get back.

I don’t know why but I just feel nervous about cancers etc
