B12 deficiency symptoms

B12 deficiency symptoms look like a list of COVID-19 symptoms: extreme fatigue, shortness of breath, rapid heart rate, numbness, tingling, or burning in either the hands, legs, or feet, and developing ulcers or sores in the mouth. Add short-term memory loss, sore tongue, backache, cough.

Harvard Health Letter describes symptoms of B12 deficiency:

strange sensations, numbness, or tingling in the hands, legs, or feet
difficulty walking (staggering, balance problems)
anemia
a swollen, inflamed tongue
difficulty thinking and reasoning (cognitive difficulties), or memory loss
weakness
fatigue
B12 And Fatigue

Severe fatigue is a very prevalent symptom of COVID-19 infection that is independent of the severity of infection. Vitamin B12 deficiency results in unremitting fatigue. More than half of surveyed COVID-19 patients report persistent and incapacitating fatigue long after they recovered from their infection.
