Cracked heels

Dry, cracked skin around your heel or foot could be a sign of thyroid problems. The thyroid is a gland that makes hormones to control parts of your body, so if your heels are really dry, it might be a good idea to check your thyroid.

Of course, dry skin can also just happen because of weather changes. But if you're also experiencing weight gain or vision issues along with dry feet, it's best to see a doctor.

Crawling or creeping sensation in your feet

If you notice unusual sensations in your legs and feet, such as crawling, creeping, or an irresistible urge to move, it could be a sign of restless leg syndrome. This chronic condition typically leads to discomfort, especially at night, making it difficult to relax or sleep. If these symptoms persist, it's important to seek medical advice for proper diagnosis and management.

Foot cramps

Foot cramps can hurt a lot, because your muscles suddenly tighten and cause pain. This usually happens when you’re working out or if you’re dehydrated. But if you’re getting cramps often, it could be because you’re low on calcium, potassium, or magnesium. To help, try eating more veggies, drinking water with minerals, and make sure to stretch your feet before bed.

Also, pregnant women often get these cramps because of all the hormonal changes they’re going through.

Always feeling cold in your feet

Cold feet are common and can be caused by various factors. It may be linked to your circulation or an inherited trait. When your body gets cold, blood vessels in your hands and feet constrict, reducing blood flow to keep internal organs warm. People with less body fat may feel colder.

Raynaud's syndrome causes blood vessels to overreact to the cold, turning your feet blue, white, and red. Poor circulation from conditions like atherosclerosis can also cause cold feet, making them appear blue or white, and causing pain in your legs when walking. Nerve damage (neuropathy) may make your feet feel cold, even if they're not. If you're concerned, consult your doctor to check for circulation or nerve issues.

Dry and peeling skin

Dry, peeling skin on your feet is often seen as a lack of care, but it could actually be a sign of a fungal infection. If left untreated, the skin can blister, and when those blisters burst, the infection can spread. If you suspect you have an athlete's foot, it's important to see a doctor to stop the fungus from growing, clear it up, and relieve your symptoms.

When the hair on your toes disappears

If you've noticed hair loss on your feet, it could be due to poor blood circulation. When circulation isn't great, the body prioritizes vital organs over the extremities, like your toes. Hair loss can also be a sign of diabetes.

Hair on your toes might seem like a nuisance, but it's actually a sign of good circulation. Healthy blood flow to your feet helps with wound healing and sensation. So, having some toe hair is a good thing. If you notice any changes, like new hair growth, moles, or blisters, it’s a good idea to mention it to your doctor.

Numbness in feet

Numbness in your feet can be caused by several conditions, like diabetes, sciatica, or nerve damage. When nerves are damaged or compressed, you may lose feeling in your foot, which can affect your balance. You might also feel tingling, pins-and-needles, or weakness.

If the numbness comes on suddenly with other symptoms like confusion, dizziness, or difficulty breathing, seek medical help right away. If numbness makes you trip or worsens over time, make an appointment with your doctor. Be sure to ask your doctor for advice and treatment options.

Pain that worsens after periods of immobility

Although the pain may be mild, it is a concerning symptom. Discomfort in the legs is often caused by poor blood circulation: in a healthy body, blood flows easily from the legs to the heart, but varicose veins interfere with this process.

Phlebologists explain that varicose veins are connected to heart health. They recommend that if you have vein issues, you should also have your cardiovascular system checked to prevent potential problems with your heart valves.

How does diabetes affect your feet?

Diabetes can affect your feet in a few ways. High blood sugar can cause nerve damage, leading to tingling, pain, or even loss of feeling in your feet. Without feeling, you may not notice small injuries like blisters or cuts, which can get infected. Diabetes can also reduce blood flow to your feet, making it hard for infections or wounds to heal. This can lead to serious problems, like gangrene, which may need amputation.

To keep your feet healthy, check them every day, wash and dry them well, wear proper shoes, and visit a podiatrist regularly. Managing your blood sugar is also key to preventing foot issues. People with diabetes need to be extra careful with their feet. Diabetes affects around 1 in 10 Americans, and most people with it — about 60% to 70% — end up having nerve problems.

Despite many warnings, people often think serious situations won't happen to them. While emergencies are rare, knowing how to respond can boost your chances of survival. Here are some essential tips that could save your life in an emergency.
