What can cause swollen itchy red hot feet and toes?

Swollen itchy red hot feet and toes can be caused by a variety of underlying medical conditions, some of which can be serious. Here are some possible causes:

1. Cellulitis: A bacterial infection of the skin and underlying soft tissues, often accompanied by fever, chills, and malaise.

2. Erysipelas: A specific type of cellulitis caused by bacteria that enters through a break in the skin. It typically appears as a spreading, red, raised area with a well-defined border.

3. Lymphedema: A buildup of fluid in the tissues due to impaired lymphatic drainage. It can occur in the feet and toes due to various causes such as chronic venous insufficiency, infection, or cancer treatment.

4. Gout: A form of inflammatory arthritis caused by the buildup of uric acid crystals in the joints, particularly the big toe.

5. Peripheral neuropathy: Damage to the nerves that supply the feet and toes, often caused by diabetes, alcoholism, certain medications, or autoimmune conditions.

6. Allergic reactions: Contact with allergens such as certain plants, insect bites, or chemicals can cause allergic reactions, leading to swelling, itching, and redness.

7. Eczema: A chronic skin condition characterized by dry, itchy, and inflamed skin, which can affect the feet and toes.

8. Athlete's foot: A fungal infection that commonly affects the skin between the toes, causing itching, redness, and scaling.

9. Psoriasis: A chronic autoimmune skin disorder that can manifest with red, scaly patches on the skin, potentially including the feet and toes.

10. Raynaud's syndrome: A condition in which the blood vessels in the fingers and toes narrow in response to cold temperatures or stress, leading to numbness, tingling, and discoloration.

11. Deep vein thrombosis (DVT): A blood clot that forms in a deep vein, often in the leg, can cause swelling, pain, and redness in the feet and toes.

12. Insect bites or stings: Bites from insects such as mosquitoes, fleas, or ticks can cause localized swelling, itching, and redness.

If you experience swollen itchy red hot feet and toes, it is essential to see a healthcare professional for an accurate diagnosis and appropriate treatment. They can determine the underlying cause and recommend the best course of action, which may include medications, lifestyle modifications, or further testing.
