does anyone get marks on their skin like this?

[Gulpingcoffee]

Or know what they are? The one with the blue circle has been there few a few months, the others have come since then and now appearing on my neck etc and across the torso. They seem permanent, like a cross between a bruise and a birthmark. Def not my bra rubbing or allergy to detergent etc.

Are they itchy?

Photo isn't great, so it's difficult to tell. Is the texture of the skin slightly different, like they have a smoother, almost silky quality to them? And they wrinkle differently to the surrounding skin if you gently press them / to one side of them? If yes,I'd get some Nizoral (shampoo) & use it as a shower gel. DH gets something very similar & apparently it's a harmless fungal thing, it's slightly annoying but it just needs treatment when it crops up, & it goes away. I'd probably see if a pharmacist could put your mind at ease as well, just to be safe.

Looks fungal.

Not at all itchy. Will try some of the suggestions thanks
