Back pain is exaggerated by tight muscles & poor flexibility. so a simple daily stretching plan will help to reduce the pain and also strengthen your back.
Stretching is best done when your muscles are warm, so a short walk will warm up your muscles.

Hold each stretch for between 30-60 seconds. It is important when stretching to concentrate on relaxing and lengthening your muscles. It doesn’t have to hurt they just need to get longer
