This morning i got a small itchy bump on my wrist, after scratching it, it spread around my wrist more. they are skin colored and flat. what is this?

Itchy Bumps: It is hard for me to say without looking. In general, widesprad, aymmetrical, red and itchy bumps tend to be caused by a virus, rather than an allergy. They often hang around for a while, and go away without treatment. If yours have lasted weeks and started to spread, i would advise that you show them to a doctor, since only in that way can you get a definitive diagnosis.
