Everyone has days when something hurts for no obvious reason. A stiff back after sleep, a headache by mid-afternoon, a strange ache that fades once you stop thinking about it.
Most of the time, these discomforts are harmless and pass on their own. The problem is that truly serious conditions often start by feeling ordinary.
That uncertainty is what worries many clinicians. According to London GP Dr Ellie Cannon, paying attention to how pain behaves can make the difference between reassurance and urgent care.
When pain signals danger
Pain becomes more concerning when it behaves differently from what you expect. Doctors look for symptoms that are sudden, unusually intense, or linked to other changes in the body.

Chest discomfort, for example, is often blamed on indigestion or anxiety, but prolonged pain that spreads or affects breathing can indicate heart or lung emergencies.
Abdominal pain follows a similar pattern. Mild soreness after exercise or a heavy meal is common. Severe, spreading pain, especially when paired with vomiting or bowel changes, can point to conditions that require rapid treatment.
The red flags doctors watch for
Dr Cannon, writing in the Daily Mail, highlighted several pain patterns that should never be brushed aside.
They are concerning not because they are common, but because of what they can represent beneath the surface.

- chest pain that persists or spreads beyond the chest
- intense abdominal pain that becomes unbearable
- back pain combined with numbness or bowel changes
- sudden, explosive head pain unlike previous headaches
- calf pain with swelling, warmth or colour changes
These signs may be linked to conditions such as heart attacks, blood clots, nerve compression, brain bleeds or serious infections.
Why timing matters
Back pain, headaches and leg pain affect millions every year and are usually harmless.
What changes the picture is speed and severity. Sudden onset, rapid worsening or pain paired with weakness, confusion or physical changes should raise concern.
Health authorities advise calling emergency services for severe symptoms and using medical advice lines for uncertainty.

As Dr Cannon notes, most pain does not require treatment, but recognising the rare exceptions can be life-saving.
