When you have hand and foot psoriasis, the skin on your hands and feet redden. Then, blisters appear. You can also get scales around the blisters. Your palms and soles can swell, crack, and bleed.
Pressure or rubbing on your hands and feet -- like from shoes that don’t fit -- can make the problem worse. After the blisters burst, they might dry up or make your skin crusty and brown.
