What are the first signs of long COVID?

Long COVID describes symptoms that continue or develop after a COVID-19 infection. Early clues can include reduced stamina, unrefreshing sleep, a foggy or slowed feeling when concentrating, and aches in muscles or joints. Symptoms may fluctuate rather than follow a steady path; activity can make some people feel worse later the same day or the next day. Other conditions, including anaemia, thyroid problems, medication effects or another infection, can cause similar complaints, so symptoms alone cannot confirm Long COVID.

Write down when the original illness occurred, which symptoms remain, what worsens them and how they affect work, sleep and daily tasks. Pace activities, take planned rests and avoid pushing through a marked worsening. A GP Consultation can review your history, examine you and decide whether tests or referral are appropriate. A Chronic Disease Review may help when symptoms continue and need coordinated follow-up.

Book an assessment for symptoms that persist, limit normal activities or are getting worse. Seek urgent help for severe breathlessness, chest pain, fainting, new weakness on one side, sudden confusion or blue lips. Call for immediate advice if a rapid deterioration follows an earlier COVID-19 illness.

Could another condition explain my fatigue or concentration problems? Which activities should I pace? Do I need blood tests or other checks? What changes should prompt urgent review?
