Understanding COVID skin problems: An Unusual Symptom of COVID-19

The COVID-19 pandemic has presented healthcare providers across the globe with a myriad of unique and unexpected challenges. One such anomaly is the appearance of a peculiar symptom: discolored and swollen toes, or what has been commonly dubbed as “COVID toes.” Although this symptom can appear in individuals of all ages, there seems to be a higher occurrence in children, teenagers, and young adults, often presenting in those who are otherwise healthy and may not have other common symptoms of COVID-19 like dry cough, fever, and muscle aches.

COVID toes present a complex picture. The affected toes or fingers exhibit purplish discoloration, swelling, and, occasionally, round brownish-purple spots. While the condition primarily affects toes, it can occasionally manifest on the fingers as well. The discoloration can commence on one or multiple digits and gradually change from a bright red colour to purple.

In terms of sensation, the symptoms vary. Some individuals with COVID toes may experience blisters, itchiness, or pain, while others may see raised bumps or rough patches of skin. Some might even observe a small amount of pus under their skin. However, a number of patients may not experience any sensation, discovering they have COVID toes only upon seeing the discoloration and swelling.

The lingering question is: how long do COVID toes last? As of now, the condition’s duration appears to vary widely. While it generally resolves without treatment, some patients may experience symptoms for months.

Another skin condition that might resemble COVID toes is chilblains, which typically arises from exposure to cold temperatures. Chilblains cause burning, itching, redness or darkening of skin, and in severe cases, sores or blisters. This is distinct from COVID toes, and it’s crucial to distinguish between the two for appropriate treatment.

Besides COVID toes, the coronavirus can induce a variety of skin reactions, which makes diagnosing COVID-19 based on skin symptoms alone challenging. There is no single characteristic rash for this disease. Patients with COVID-19 have presented with a myriad of skin conditions, from hives-like and patchy rashes to itchy bumps and blisters similar to chickenpox, and even a lace-like pattern on the skin.

These rashes generally last between 2 to 12 days, with a median duration of 8 days. However, this can vary significantly among individuals. Some rashes may cause itching, and certain types might necessitate medical treatment.

The query remains, why does COVID-19 affect some people’s skin and not others? The answer, unfortunately, is unclear at this time. The novel nature of the coronavirus means doctors are still uncovering how it impacts different parts of the body, including the skin. Dermatologists worldwide are at the forefront of these investigations, endeavoring to understand the myriad ways in which COVID-19 might present itself.

If you observe any skin symptoms such as COVID toes or a rash, it is essential to consult with your doctor. It is crucial to remain vigilant as our understanding of COVID-19 continues to evolve. Stay informed, and remember: your health and safety are paramount.
