What is lumbago?
Basically, low back pain can be defined as pain in the lower back, that is, in the lower region of the spine near the pelvis. They can be classified by duration into acute or chronic.
When they last four to six weeks it is considered acute, and chronic when it lasts longer than 12 weeks. About 65-90% of adults will experience an episode of acute low back pain throughout their lives, it can occur at any age, with a peak incidence occurring between 35-55 years of age.
