Acute pain starts suddenly and usually feels sharp. Broken bones, burns, or cuts are classic examples. So is pain after giving birth or surgery.
Acute pain may be mild and last just a moment. Or it may be severe and last for weeks or months. In most cases, acute pain does not last longer than 6 months, and it stops when its underlying cause has been treated or has healed.
If the problem that causes short-term pain isn’t treated, it may lead to long-term, or “chronic” pain.
