Backache is described as mild to severe pain or discomfort occurring in the lower back or lumbar area. More strain is placed on the lower part of the back because it carries the weight of the upper body in addition to your own weight. The pain may be caused by an accident, injury, swelling, degenerative changes, congenital or metabolic disease or development of a tumor. Often the pain and discomfort becomes worse when a person bends forward.
Older people may find that they also experience problems in their legs because of the undue pressure on the spinal nerves. Most cases of backache may be acute or chronic. Acute backache starts suddenly and severely, and lasts for a short period of time. There are often recurrences that may lead to chronic backache. Chronic back ache may be triggered by the slightest movements and is more stubborn, often persisting for three months or longer.
