Here are some of the top reasons for your lower back pain:
When you get a crack in one of the spinal disks, the rubbery cushions that are located between the vertebrae may cause back to pain or play a role in developing the back pain. Your spinal disks protect the stacked vertebrae from rubbing against each other. Annulus, which is the outer layer of each disk, is normally tough and pliable, while nucleus, which is the inner layer, is soft. Back pain can also occur when your spinal disk starts to gradually develop age related changes that may contribute to your back aches. The annulus is not stretchy because there is less water within it, and there are chances of it cracking (herniated), and when this happens then the nucleus bulges out, presses on the nerves and causes your back to pain.
Degenerated Changes in the Spine
You may face degenerative changes that will develop in the vertebrae when your spinal disks become flatter and less flexible. When the cushioning that these disks usually provide dwindle, the joints (facets) between vertebrae press tightly against each other, thus causing you to suffer from back pain and stiffness. What your body will do is compensate for these changes by building new bone so as to support the area where the pressure is increased. People experiencing such a pain should be careful to sleep well, as much of wrong posture while sleep causes this.
When you age, the amount of calcium decreases in your bones. Thus, this automatically lowers the density or mass of your bones, making them porous and brittle, and a condition that is known as osteoporosis. For those who have osteoporosis, daily lifting and other routine activities are a strict no-no as it can cause compression fractures , such as cracks, usually on the forward-facing sides of one or more vertebrae, and this compression fractures often lead to back pain.
