Psoriasis happens when skin cells grow too fast and then pile up on the skin’s surface. It’s a long-lasting condition that usually runs in families. There are a few different types, and itchiness of the palms and soles is a common symptom. If you have psoriasis, you may also have:
- Patches of red skin, bumps filled with puss, or silver scales
- Painful, swollen, or stiff joints
- Soreness of the affected area
- Itchiness in other places like your elbows, knees, lower back, and face
