Long COVID: What We Know So Far About Its Causes and Treatment | Ask Doc Esser and Anne
Even mild COVID-19 infections can lead to lasting symptoms in some people — chronic fatigue, brain fog, and air hunger — sometimes meeting criteria for ME/CFS (Myalgic Encephalomyelitis / Chronic Fatigue Syndrome). Doctors still cannot confirm Long COVID with a single test, and most treatments help manage symptoms rather than cure the underlying problem. Pacing and realistic acceptance are core recovery strategies; most patients improve meaningfully within a year.
