Back injuries are a part of everyday life. They can cause a sharp pain or a dull ache and can be accompanied by a tingling, numbness, or burning sensation. You also may feel weakness, pain or tingling in your pelvis and upper leg-a condition known as sciatica. The spine is quite good at dealing with back injuries. Minor injuries usually heal within a day or two. Some pain, however, continues. What makes it last longer is not entirely understood, but researchers suspect that stress, mood changes and the fear of further injury may prevent patients from being active and exacerbate the pain. Our neck, also called the cervical spine, begins at the base of the skull and contains seven small vertebrae. Incredibly, the cervical spine supports the full weight of your head, which is on average about 12 pounds. While the cervical spine can move your head in nearly every direction, this flexibility makes the neck very susceptible to pain and injury. The neck’s susceptibility to injury is due in part to bio-mechanics. Activities that affect cervical bio-mechanics include extended sitting, repetitive movement, accidents, falls and blows to the body or head, normal ageing,and everyday wear and tear.
