I have some very little chicken pox on my wrist and i had vaccine before, what should i do?

Chicken pox: if your wrist is the only location for your rash then most likely not chicken pox

Who said cpx ?: The skin is somewhat limited in what it will do as an abnormality.It can change color, form bumps or blisters, get oozy or dry. These limited outcomes can be triggered by many separate triggers. A blistering rash located only on your wrist is more likely a contact dermatitis than some viral illness.Keep it clean and it should self repair over 1-2 wks.
