Avoidance is the most useful technique to use for repeated back pain suffers.
If discomfort is felt on waking up in the morning pay special attention to the sleeping position. Try not to sleep on the stomach but if this cannot be avoided place a small pillow under the abdomen to raise the back slightly. The best position for the back is to sleep on the side and draw one or both knees up towards the chin.
If you are prone to back problems never stretch, lift heavy objects and when well, always try to keep gently moving, never staying in one position for too long.
One technique worth considering is to massage the feet along the instep. This promotes circulation in the area of the back and may relax any tension which has built up there.
For severe pain make an appointment with your chiropractor at the earliest opportunity!
