Some people have back pain that lingers on and on. Some suffer from recurring pain. This is called chronic backache. The following tips are particularly helpful for those with chronic pain though acute pain sufferers can benefit from them as well.
Make sure your bed does not sag in the middle when you sleep in.
A modern waterbed which is adjustable and does not make a lot of waves is excellent for most types of back trouble.
The best position for someone resting in bed is called the lazy "S" position. Put a pillow under your head and upper neck, keep your back relatively flat on the bed and then put a pillow under your knees.
Stick a pillow between your knees when you sleep on your side. The pillow stops your leg from sliding forward and rotating your hips, which puts added pressure on your back.
