English: you have blisters or cracks on the palms of your hands or soles of your feet you can't explain, see a skin doctor (dermatologist). You may have palmoplantar pustulosis (PPP).

This is an autoimmune disorder. That means your body sends antibodies to fight your own cells.

There's no cure for PPP, but it can be treated and may go away and never return. However, it can come back.

Symptoms

PPP first appears as tiny blisters with yellow pus. Eventually, these turn brown and become scaly. PPP can also cause painful cracks in your skin. The blisters and sores can make it hard for you to walk comfortably or to use your hands without pain.

Causes

The cause is unclear, but there's a known link between PPP and smoking. Studies show that up to 90% of people with the skin condition smoke or once did.

Nicotine in tobacco products can affect your skin cells and cause inflammation in your sweat glands, especially on your hands and feet. If you stop smoking, your symptoms may get better.
