5 Things Your Feet Are Telling You About Your Health

By Lance Silverman, MD, Special to Everyday Health

Your feet are amazing diagnostic tools that your doctor can use as clues potentially pointing to a whole host of health problems.


If you notice any of the following telltale signs or symptoms in your feet, you may want consult your doctor:

1. Dry, Flaking Skin



2. Balding Toes

While toe hair is more common and visible in men, women generally have fine hairs on their toes as well. If you notice that your toes are losing a little bit of hair, or if they've gone completely bald, it could be a sign of poor blood flow. One cause of insufficient blood supply to the feet and toes is peripheral arterial disease, or PAD for short.


If you suspect PAD, see a doctor. You can combat symptoms of PAD by giving up smoking, maintaining a balanced diet, getting regular exercise, and managing other health conditions, like hypertension or diabetes, that can contribute to the condition. If you already have it, try these foot care tips.

3. Foot Numbness

Like toe baldness, foot numbness due to a lack of blood flow in the area can be a sign of PAD. You've probably experienced numbness in your feet if you sat in one position for too long, or if you fell asleep at an awkward angle. But if it happens regularly or while you're active, it’s a problem you shouldn't ignore.


If you have irregular bouts of foot numbness, and wounds on your feet just don't seem to heal, talk to a doctor. To promote healthy blood flow and help prevent type 2 diabetes, be sure to get regular exercise and reach for healthy foods.

4. Black Spots or Lines Under Your Toenails

When someone steps on your toes or you drop a heavy object onto your foot, you’ll most likely have some toenail discoloration. Dark discoloration under your toenail isn't typically concerning if you know what caused it.

But if you notice discoloration — or black and brown lines — under a toenail and you don't remember injuring your toe, you might want to talk to your doctor. Dark, vertical lines under a toenail could be a sign of a hidden melanoma. We’re getting better at fighting cancer every day, but hidden melanomas often go overlooked and untreated.

Toenail discoloration could also be caused by a fungal infection, and while that's much less severe than a potential cancer diagnosis, you should not ignore it. My advice is to check your toenails for discoloration every time you cut your nails.

5. Morning Foot Pain

A number of patients have asked me why they experience foot pain in the morning. Burning or shooting foot pain that happens when you take your first few steps out of bed can indicate of a number of potential issues.

First, it could be a sign of rheumatoid arthritis (RA), which inflames your joints and can cause pain even in the small joints of your feet. You can control foot pain and other of rheumatoid arthritis symptoms with medication and regular exercise; ask your doctor about this if you haven’t already.


Lastly, morning foot pain could be caused by a muscle cramp. As with plantar faciitis, you can avoid foot cramps by stretching your foot muscles before you get out of bed.


Cramps mean your body isn't getting enough calcium, potassium, and magnesium. You can help prevent morning foot cramps by eating a balanced diet and drinking water before heading to bed.
