Not all pain is created equal. While many aches fade on their own, certain types of persistent or sudden pain can be the body’s way of flagging a condition that needs prompt medical attention. Here are seven warning signals worth taking seriously.

In brief
- —A sudden, severe headache may signal a ruptured aneurysm
- —Leg swelling with pain could indicate a dangerous blood clot
- —Chest pain with dizziness or cold sweats warrants immediate attention
