Quick answer
What could muscle pain mean?
Muscle pain (myalgia) is usually caused by overuse, tension, minor injury or viral infections. It often improves with rest, hydration and simple pain relief. See a GP if pain is severe or lasts more than a few weeks, and seek urgent help for widespread pain with weakness or dark urine.
What is muscle pain?
Muscle pain, or myalgia, can affect a small area or many muscles at once. It may feel like aching, cramping or tenderness and is one of the most common reasons people take painkillers.
Most muscle pain is benign and linked to everyday causes. A small number of cases relate to medicines, metabolic problems or serious muscle breakdown.
Common causes of muscle pain
Overuse and strain from exercise, lifting or repetitive work are frequent triggers. Poor posture and stress-related tension commonly affect the neck and shoulders.
Viral infections including flu and COVID-19 often cause generalised aching. Fibromyalgia causes chronic widespread pain with fatigue and sleep problems. Some medicines, notably statins, can cause muscle symptoms.
Easing muscle pain at home
Rest the affected area briefly, then resume gentle movement. Warm baths, heat packs and stretching may help. Paracetamol or ibuprofen can reduce pain if appropriate.
Stay hydrated, especially after exercise. A physiotherapist can advise on posture and strengthening if pain is recurrent.
When to see a GP about muscle pain
See a GP if muscle pain is persistent or unexplained, if it comes with weakness, or if it seems linked to a new medicine. Dark urine, severe muscle pain after extreme exercise, or rapidly worsening weakness all need urgent medical attention.
Common questions about muscle pain
- Why do muscles ache after exercise?
- Muscles often ache after exercise because of delayed-onset muscle soreness (DOMS), which peaks 24–48 hours after unfamiliar or intense exercise as the muscles repair. It is normal and improves with light movement and rest.
- Can stress cause muscle pain?
- Yes, stress can cause muscle pain, because tension and anxiety often lead to tightness in the neck, shoulder and back muscles. Relaxation, stretching and addressing the stress itself can all help, alongside treating any underlying mood symptoms.
- When could muscle pain be serious?
- Muscle pain could be serious if it is severe and comes with dark urine or significant weakness, or if it starts after beginning a new medicine such as a statin. These situations may need immediate assessment, so seek urgent help.
- What helps general muscle aches from a cold or flu?
- Rest, plenty of fluids, gentle stretching and simple pain relief with paracetamol or ibuprofen (if suitable for you) usually help the muscle aches that come with a cold or flu. Symptoms typically improve as the infection clears.
