What causes hand and foot psoriasis?

ANSWER

Hand and foot psoriasis is also known as pustular psoriasis. It gets its name from the whitish-yellow blisters, or pustules, it causes.

The blisters are not contagious, but they can be painful. They can show up anywhere on your body, but mostly on the palms of your hands and soles of your feet.
