Lower Back Pain When I Sleep on My Back

I get lower back pain when I sleep on my back and I believe for me it is because of years of straining myself. I have had a bad back for quite some time, mostly from the work I do and the strains I get from there. Recently though I discovered that when you sleep on your back your body comes out of alignment. The reason for this is because of different areas that we carry our weight. Most of the time our shoulders and hips will have the most weight on them. When laying on your back this causes the mattress to sink in those areas, but sink so much that you end up with no support under your back. The only mattress I could find to relieve this pressure is called a gel foam mattress. A gel foam mattress in a little more expensive then a regular high end mattress, but with the life span you actually save money and save your back.
