Hi,i am having huge cracks on heels n feet.they are painful. it has been three years i am having this problem! is it a infection or something? help??!

Not an infection: Cracked heels are caused by excessive buildup of dead skin. When the dead skin gets too thick the friction causes tearing of the living layer of the skin, leading to an open wound and pain. These can become infected but are painful even without an infection. There are many types of prescription strength creams that can help. I recommend you see a podiatrist for evaluation and treatment.
