Video: Treating back pain

Three out of every four Americans will have back pain at some point during their life.

Many cases of back pain are due to muscle strain that--with treatment--can feel better in just a few weeks.

Other causes of back pain--herniated disc, injured vertebra or arthritis--can be more serious and require more complex treatment.

Here are a few ways to make your back feel better:

• Keep moving. 
• Stand or sit up straight. 
• Try relaxation techniques. 
• Apply heat or cold packs.
• See your doctor.
