What do twinges in your back mean?

Muscle strains are the most common cause of lower back pain. Strains happen when you stretch or tear a muscle or tendon. They're usually caused by injuries, either from sports or making certain motions, such as lifting a heavy box. Muscle strains can also cause muscle spasms, which may feel like sharp jolts of pain.

How do I get rid of twinges in my back?

For minor aches and pains or twinges after an injury or strain, it's usually sufficient to take a pain reliever — either acetaminophen (Tylenol) or a nonsteroidal anti-inflammatory such as ibuprofen (Advil) — and continue normal activities.
