Life Style Modifications:
Concentrate on your ergonomics like posture and movements
Avoid forward bending. To lift anything take the support of your knees by bending them.
Sleep on supine position to avoid back stiffness, place pillows below your knees to avoid muscular tension on discs and surrounding tissues to relax.
Avoid long standings and long sittings to prevent muscle fatigue. Keep yourself busy with breaks in between your work schedule.
Keep your weight under control to prevent gravity shifts of your spine.
These are some life style modifications you can follow to prevent pain.
