3. Numbness
Loss of sensation in the feet can make it difficult to notice injuries, increasing the risk of infections and other complications.
Common causes include:
- Diabetes
- Nerve injuries
- Poor circulation
- Herniated discs
- Multiple sclerosis (less commonly)
Ongoing numbness should always be assessed by a healthcare professional.
4. Swollen Feet
Foot swelling can occur after long periods of standing, during pregnancy, or after eating a high-sodium diet. However, persistent or severe swelling may indicate a more serious medical condition.
Possible causes include:
- Venous insufficiency
- Heart disease
- Kidney disease
- Liver disease
- Pregnancy
- Certain medications
Seek urgent medical care if swelling develops suddenly, affects only one leg, or is accompanied by chest pain, difficulty breathing, or severe pain.
5. Constantly Cold Feet
Cold feet are sometimes caused by chilly weather, but if your feet remain cold even in warm environments, poor blood flow or another medical condition may be responsible.
Possible causes include:
- Peripheral artery disease
- Poor circulation
- Diabetes
- Thyroid disorders
- Smoking-related vascular disease
A healthcare provider can determine whether circulation or another underlying issue is contributing to your symptoms.
6. Foot Sores That Won’t Heal
Cuts, blisters, or sores that heal slowly deserve prompt attention, especially for people living with diabetes.
