How to Explain Chronic Fatigue to Your Doctor
Chronic fatigue — especially in the context of ME/CFS — is one of the most misunderstood and dismissed conditions in primary care. Many patients are told it is "just stress" or given lifestyle advice before proper investigation. The key to being taken seriously is specificity: not "I'm tired all the time" but "I experience post-exertional malaise — a worsening of all symptoms 12–48 hours after even minor exertion — that can leave me bed-bound for days." This guide helps you build that vocabulary.
