Hi i have dark blue/ purple veins on the inside of my hand and they feel itching from within is that normal?

Doesn't sound normal: Sounds like the way my hands feel after being in the snow, but it says you are in Australia, so unless you work in a cold environment (meat section of grocery store etc) it is unlikely this is a response to low temperature! Could possibly be an allergic response causing the itching. Best thing is to have a Dr examine your skin, check the circulation in hands and determine the best treatment.
