Back Injuries
Your back is an intricate structure of bones, muscles, and other tissues extending from your neck to your pelvis. Back injuries can result from sports injuries, work around the house or in the garden, or a sudden jolt such as a car accident. The lower back is the most common site of back injuries and back pain. Common back injuries include

Sprains and strains
Herniated disks
Fractured vertebrae

These injuries can cause pain and limit your movement. Treatments vary but might include medicines, icing, bed rest, physical therapy or surgery. You might be able to prevent some back injuries by maintaining a healthy weight, lifting objects with your legs and using lower-back support when you sit.
