LITTLE ROCK, Ark. (KTHV) -- Believe it or not, your feet are a good indicator of your overall health. Here are five things your feet say about your health from Health Central.

1. No hair on your feet or toes - "Bald" feet can be a sign of poor circulation as a result of vascular disease. Although the hair may never return, which isn't necessarily a terrible thing, you'll want to see a doctor about improving your circulation and getting your vascular health in check.

2. A persistent sore on your foot - If you have a wound on your foot that just won't heal, you could be at risk for diabetes. Elevated blood glucose levels over time can lead to nerve damage in the feet. Left untreated, this can lead to serious consequences, even to amputation.

3. Cold feet - For women, cold feet may indicate an "under-functioning" thyroid problem, which is the gland that regulates temperature and metabolism. Poor circulation is another possible cause for both men and women.

4. Thick, yellow toenails - If one or more of your toenails starts to thicken, change color, and separate from the skin, it probably means you have a fungal infection. People with diabetes, rheumatoid arthritis, and other immune deficiencies may be more susceptible. See a podiatrist for care and treatment.

5. Numbness in both feet - Having a persistent "pins and needles" feeling in your feet, or actual loss of feeling, can be a sign of peripheral neuropathy. This could mean there has been damage to your nervous system. See your doctor and explain your symptoms.
