Most muscle pain isn’t a sign of anything serious.
It usually eases within a few weeks with gentle movement, warmth, and time. A few signs, though, mean it’s worth being checked rather than self-treating.
- The pain hasn’t improved after a few weeks, or keeps getting worse
- It wakes you at night, or rest and changing position don’t ease it
- You have numbness, tingling, or weakness that spreads or won’t settle
- It began after a significant fall or accident
- You also have fever, unexplained weight loss, or feel generally unwell
- You have a history of cancer
- You lose control of your bladder or bowels, or feel numb around the groin or inner thighs
- A limb becomes suddenly weak or numb
- You have chest pain, or pain spreading to the arm, jaw, or back with breathlessness or sweating
- You have a sudden, severe headache unlike any before
