It is important that you do not sleep in the same position each night if you suffer from back pain. By sleeping in the same position all night, you are allowing your spine to stiffen up which can cause back pain. Be sure that you replace your mattress and pillow regularly.
No matter what the reason, if you suffer from back pain and you have to bend over, be sure to do so with your knees and not your back. Many people suffer from back strains or pains because they bend over using their back, which puts too much pressure on the spine.
