My name is Arnold, I m 66 years old.... I can t go to bed because I can t lay down, my lower back hurts as soon as it its the mattress, I get excruciating pain before the spine curve flattens against the mattress,then I have problem turning and lifting up.... the same thing happens if I try to lay on my chest. This has been going on for at least 3 months. I laid a hardwood floor on 2d floor of a house, I fell to my face during the renovation but it did not affect me untill I completed the job. Then the low back pain began. Thanks for this opportunity Arnold
