Use good posture, which generally means that your ears, shoulders, and hips are in a straight line. Slumping or slouching after a strain or injury in your back can make back pain worse.
If you've tried home treatment for several days in a row and it hasn't helped, call your health care provider. You may need physical therapy or other treatment to prevent more injuries.
To help prevent another injury, review your work area. Be sure it is set up in the best way possible to fit you and the job your are doing. You may be able to get more information about workplace safety and ergonomics from your human resources department at work or from your state's Department of Labor.
