Dr. Thomas Gut, D.O., Associate Chair of Medicine at Staten Island University Hospital shares, " This is generally seen in severe COVID cases. Likely caused by a blood flow and clotting abnormality that COVID can trigger. Uncommon with Omicron and later variants." Dr. Vivek Cherian, a Chicago based Internal Medicine Physician adds, "COVID toes, which are more commonly seen in children, is a skin condition. This is a type of skin condition that is associated with swelling, blister-like bumps or discoloration of the toes and/or fingers as well as swelling or blisters."

Dr. Gut says, "palpitations can be a warning sign of cardiac damage. However, generally not serious and do improve with healing time and stress reduction."

According to John Hopkins Medicine, "After you have had COVID-19, if you are experiencing a rapid heartbeat or palpitations you should contact your doctor. A temporary increase in heart rate can be caused by a lot of different things, including dehydration. Make sure you are drinking enough fluids, especially if you have a fever. Symptoms of a rapid or irregular heart rhythm may include:

–Feeling your heart beat rapidly or irregularly in your chest (palpitations)

–Feeling lightheaded or dizzy, especially upon standing

–Chest discomfort."

Dr. Cherian shares, "Hair loss can occur even several months after a COVID infection. The theory for why this is because of overstimulation of hair follicles during an active infection and ultimately leads to shedding phase post-infection."

According to Dr. Cherian, "The BA.2 sub-variant of Omicron accounts for over half of new U.S. coronavirus cases, and is now the dominant strain in this country. Its rapid growth is attributed at least in part to its mutations for the spike protein on the virus's surface, which are not found in BA.1. BA.2 is more transmissible than BA.1, the good news is that it has not been shown to cause more severe illness and vaccines continue to offer a high degree of protection from severe disease, and even more so if you've had a booster."
