Understanding inflammation

Inflammation is part of the immune system’s response to an injury or infection. A sprained ankle, for example, can become warm and swollen as the body responds.

What do acute and chronic mean?

Acute inflammation begins quickly and usually settles as the injury heals or the infection clears. Chronic inflammation persists and can have several causes. A symptom alone cannot tell you which process is involved.

When to ask for advice

If swelling, pain or stiffness persists, keeps coming back or has no clear cause, speak with your GP. A pharmacist can help with questions about medicines or supplements you already take.
