Since the onset of the SARS-CoV-2 pandemic, the medical community has continuously uncovered new ways COVID-19 affects the human body. One of the more unexpected areas of impact? The feet and toes. Dr. Randall Thomas’s groundbreaking research, recently published in the Journal of the American Podiatric Medical Association (JAPMA), delves into this unique phenomenon, commonly called “COVID toes,” providing crucial insights into how the virus can manifest in the foot and ankle.
“COVID toes” is a term used to describe a condition in which patients develop skin changes and nerve-related pain in their toes. These symptoms, ranging from burning pain to hyperpigmented lesions, can occur even before a formal COVID-19 diagnosis, making them a vital early indicator for some.
Dr. Thomas’s study emphasizes the rare, yet notable emergence of such symptoms linked to COVID-19’s effect on small blood vessels and nerves in the toes. Although these manifestations are not commonly seen, understanding their presentation can help foot and ankle specialists identify COVID-19-related complications earlier in patients who exhibit these signs. This early recognition can lead to more timely and appropriate management of symptoms, potentially improving patient outcomes.
The research outlines that imaging studies reveal further details in addition to the visual changes in the toes. MRI scans conducted on patients with “COVID toes” show a pattern of distal-to-proximal bone marrow edema (swelling) in the distal phalanx of all toes. This edema is like what is observed in patients with vascular issues, suggesting that COVID-19 may contribute to a vasculopathy-like condition in the foot.
Dr. Thomas’s research followed patients over time, revealing that symptoms typically emerge four weeks after a COVID-19 diagnosis and resolve by the 12-week mark. Patients may experience discomfort and noticeable changes in their toes during this period, but the condition tends to be self-limiting.
Although rare, “COVID toes” highlight the importance of recognizing cutaneous and neural symptoms in the lower extremities during a global pandemic. For podiatrists and orthopedic foot and ankle specialists, understanding the possible connection between COVID-19 and foot-related complications is crucial for early diagnosis and appropriate management.
This article reminds us that COVID-19 can affect the body in unexpected ways, and healthcare professionals should remain vigilant in identifying symptoms that might otherwise be overlooked.
