You should see a doctor if you see any unusual signs on your feet.

Taking a closer look at the feet and observing any abnormalities can tell us a lot about a person's overall health and well-being. Some diseases will have symptoms that manifest through the feet.

The foot is responsible for supporting the body's weight, helping to maintain balance and movement, and has a very complex structure. The foot has 26 bones along with many joints, muscles, ligaments, nerves and other components, according to the health website Verywell Health (USA).

Persistent numbness and tingling in the feet is a sign that the nerves are being compressed or damaged.

People should see a doctor if they notice the following signs on their feet:

Cold feet and toes

Constantly feeling cold feet and toes can be a sign of vascular disorders. This is caused by the effects of type 2 diabetes, smoking, peripheral artery disease, and circulatory problems. Vascular disorders will reduce blood flow to the feet, leading to constant feeling cold.

Numbness and tingling

Numbness and tingling in the feet is completely normal, especially when sitting for a long time. However, if this feeling lasts for more than a few minutes and does not go away, or occurs frequently, you should see a doctor. The cause may be peripheral neuropathy, vitamin B12 deficiency, spinal stenosis, or nerve compression.

Swelling

Swelling in the feet or ankles is a sign of high blood pressure. However, this symptom can also be caused by congestive heart failure, kidney failure, or liver failure.

Dark skin

Itchy, black, flaky skin on the legs and feet may be caused by athlete's foot. If left untreated, this condition can lead to infection and inflammation of the skin, forming painful blisters. If left untreated, the infection can spread to other areas of the body.

Foot ulcers

Any foot ulcer that is slow to heal or does not heal at all may be a sign of type 2 diabetes. Foot ulcers can also be caused by venous insufficiency, peripheral neuropathy, basal cell carcinoma, or squamous cell carcinoma.

Nail pitting

Small holes appearing on fingernails and toenails can be a sign of psoriasis or psoriatic arthritis. When seeing this sign, the sufferer needs to see a doctor for early treatment, according to Verywell Health.
