itchy rash

i have an itchy rash about the siza of a quarter on my wrist and no where else on my body. about  3 days ago it seemed like the original place of the rash is healed with a mild scar but the bumps are moving farther in a circle. they are moving slowly. i have never had a rash like this. when i scratch it. it bleeds, there is no pus or water coming out. what is it?

Hi,

You should consult your doctor for a clinical examination. Nothing can be said with surety without having a look at the lesions.

This could be dermatitis, eczema, insect bite, etc.

Apply calamine lotion at the sites, do not scratch it as it would cause superadded secondary infection.

Let us know about what your doctor advises and post us about how you are doing.

Regards.
