The blisters range from pen point [ball point tip] to about 3/8 in. maybe bigger, they present in clusters, at this point it would be easier to list the places it's not [palms of my hands and below the ankle. And they itch, bad, once the skin is broken they continue to drain, clear fluid. Some blister up again most scab over and continue to itch, might be new blisters close by might be regular healing. I have one more question. If it is psoriasis would it start as 3 dots on my elbow to almost covering my entire legs, back side, arms, neck and forehead with patches on shoulders, chest and crotch in about 18 months? If so is this common? Thank you for any help. Steve.
