Body Aches After Illness: Rest or Move?

Short answer: for body aches after illness, while you're unwell, rest and drink plenty of fluids; once you're better, gentle movement helps you ease back in, and anything sharp or worsening needs a doctor.^[11][6]

Body aches after illness: what to know

• While you have symptoms: the NHS flu advice is rest and sleep, plenty of fluids, and paracetamol or ibuprofen for aches.^[11]
• Stay home if you have a high temperature or can't manage normal activities.^[11]
• Returning to activity: start low, around 50% effort, add no more than about 10% a week, and build in rest days.^[6][7]
• Mild stiffness that fades is usually fine; sharp or worsening pain means stop.^[6]

When to see a doctor

See a doctor if symptoms haven't improved after 7 days, or sooner if you are 65 or over, pregnant or recently gave birth, have a long-term condition, feel very unwell or are short of breath.^[11] Call 999 (in India, an ambulance) for sudden chest pain, severe breathing difficulty or coughing up blood.^[11]
