Understanding COVID Toes: Causes and Symptoms
Know all about covid toes, causes, symptoms, how to diagnose it and manage the covid toes. Learn how you could prevent it.
Introduction
COVID-19 has brought many unexpected symptoms to light, one of which is "COVID toes." If you’ve noticed red, swollen, or painful toes (or fingers) during or after a COVID-19 infection, you might be experiencing this condition. While it may sound unusual, COVID toes are a real and documented symptom, especially in younger individuals and those with mild or no other COVID symptoms.
In this article, we’ll break down everything you need to know about COVID toes—what they are, why they happen, and how to manage them.
What Are COVID Toes?
COVID toes refer to a skin condition where the toes (and sometimes fingers) become discolored, swollen, and sometimes painful or itchy. The affected area may look:
Red or purple (similar to frostbite)
Swollen
Bumpy or rash-like
Blisters or pus-filled bumps in severe cases
This condition is medically known as "pernio" or "chilblains," which typically occur due to cold exposure. However, in the case of COVID toes, the symptoms appear without cold weather, suggesting a link to the virus.

What Causes COVID Toes?
While the exact cause is still being studied, researchers believe COVID toes may result from:
1. Inflammation & Immune Response – The body’s immune system may overreact to the virus, leading to swelling and discoloration in small blood vessels.
2. Microclots in Blood Vessels – Some studies suggest tiny blood clots in the toes could cause discoloration.
3. Viral Infection of Skin Cells – The virus might directly affect skin cells, triggering the reaction.
COVID toes are more common in:
Children & young adults
People with mild or no other COVID symptoms
Those with strong immune responses
Symptoms of COVID Toes
The most common signs include:
Discoloration (red, purple, or blue toes)
Swelling
Pain or tenderness
Itching or burning sensation
Blisters or dry skin in severe cases
Symptoms can last from a few days to several weeks, even after recovering from COVID-19.
How Are COVID Toes Diagnosed?
If you notice these symptoms, especially after a COVID infection or exposure, consult a doctor. Diagnosis usually involves:
Physical examination (checking skin changes)
Review of COVID-19 history (recent infection or exposure)
Blood tests or skin biopsy (in rare cases to rule out other conditions)
Most cases are mild and resolve on their own, but if symptoms worsen, medical advice is recommended.
How to Manage COVID Toes at Home
Since most cases are mild, home care can help relieve discomfort:
1. Keep the Area Warm & Dry
Avoid cold exposure.
Wear warm socks (but not too tight).
2. Apply Moisturizer
Use fragrance-free creams to soothe dry or cracked skin.
3. Elevate Your Feet
Helps reduce swelling.
4. Over-the-Counter Pain Relief
Acetaminophen (Paracetamol) or ibuprofen can help with pain and inflammation.
5. Avoid Scratching
Scratching can worsen irritation.
6. Monitor for Infection
If blisters break or show signs of infection (pus, increased pain), see a doctor.
When to See a Doctor?
Most cases improve on their own, but seek medical help if:
Severe pain or swelling
Open sores or signs of infection
Symptoms last more than 2-3 weeks
Discoloration spreads to other body parts
Your doctor may recommend:
Topical steroids (for severe inflammation)
Blood thinners (if microclots are suspected)
Further testing if symptoms persist
Can COVID Toes Be Prevented?
Since the exact cause is unclear, prevention is difficult. However, general COVID-19 precautions can help:
Get vaccinated (reduces severe COVID risks)
Practice good hygiene (wash hands, wear masks if needed)
Boost immunity (healthy diet, sleep, hydration)
Final Thoughts
COVID toes are a strange but usually harmless symptom linked to COVID-19. While they can be uncomfortable, most cases resolve without treatment. If you experience persistent or worsening symptoms, consult a doctor for proper guidance.
