I have small sores and dead skin under my foot and when i get to pill it off it hurts. what could this be? and what kind of doctor can i see for this issue?

PCP/podiatrist: You may see your primary care provider or a podiatrist. If you are diabetic, it is important to seek care without delay. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
