Treatment of ongoing back problems must be
directed at the cause. This may mean losing
weight (because being overweight can make back
pain worse), getting your muscles in better
shape, and improving your posture when you're
sitting, standing and sleeping.
Sit in chairs with straight
backs or low-back support. Keep your knees a
little higher than your hips. Adjust the seat
or use a low stool to prop your feet on. Turn
by moving your whole body rather than by twisting
at your waist.
When driving, sit straight and move the seat
forward. This helps you not lean forward to
reach the controls. You may want to put a
small pillow or rolled towel behind your lower
back if you must drive or sit for a long time.

If
you must stand for long periods, rest 1 foot
on a low stool to relieve pressure on your lower
back. Every 5 to 15 minutes, switch the foot
you're resting on the stool. Maintain good posture:
Keep your ears, shoulders and hips in a straight
line, with your head up and your stomach pulled
in.
The best way to sleep is
on your side with your knees bent. You may put
a pillow under your head to support your neck.
You may also put a pillow between your knees.
If you sleep on your back, put pillows under
your knees and a small pillow under your lower
back. Don't sleep on your stomach unless you
put a pillow under your hips.
Use a firm mattress. If your mattress is
too soft, use a board of 1/2-inch plywood
under the mattress to add support.
Some specific exercises can help your back.
One is to gently stretch your back muscles.
Lie on your back with your knees bent and slowly
raise your left knee to your chest. Press your
lower back against the floor. Hold for 5 seconds.
Relax and repeat the exercise with your right
knee. Do 10 of these exercises for each leg,
switching legs.
While some exercises are specific for your
back, it's also important to stay active in
general. Swimming and walking are good overall
exercises to improve your fitness.
