Does influenza cause muscle aches?

Flu aches often involve more than one area, such as the back, arms, legs, or shoulders, and may make ordinary movement feel demanding. They result from the body's response to the viral illness. Muscle aches can also follow exertion, injury, other infections, and medicine effects, so aches alone cannot confirm influenza.

Rest, drink fluids regularly, and avoid strenuous exercise until you feel recovered. Gentle position changes, a comfortably warm room, and light clothing can make resting easier when fever is present. A pharmacist can help you choose pain or fever relief that is appropriate for your age, health conditions, and other medicines. Follow the product directions and avoid taking more than one product containing the same active ingredient.

Get urgent help for breathing difficulty, chest pain, confusion, a stiff neck, fainting, severe dehydration, or muscle pain with profound weakness. Arrange medical advice if symptoms are getting worse rather than easing, a fever returns after improvement, or you have a condition that raises the risk of becoming seriously unwell from respiratory infections.

Describe where the aches are, whether they began suddenly, and whether you also have cough, fever, sore throat, or fatigue. Tell the clinician about recent injuries, new medicines, pregnancy, and long-term conditions so they can judge whether any further assessment is needed.
