Glossary - Acute lower back pain
Acute low back pain (LBP) is defined as low back pain present for up to six weeks. It may be experienced as aching, burning, stabbing, sharp or dull, well-defined or vague. The intensity may range from mild to severe and may fluctuate. The pain may radiate into one or both buttocks or even into the thigh/hip area.
Low back pain may begin following a strenuous activity or trauma. It may begin suddenly or develop gradually. At least 75% of individuals experience a significant episode of LBP at some point in their lives.
The cause of LBP may be multifactorial. Any structures in the spine discussed above can hurt such as muscles, soft connective tissue, ligaments, facets, disc and others. Most acute LBP resolves in the first 6 to 8 weeks. Most causes of the LBP are benign and resolve on their own.
The doctor needs to be consulted rapidly if weakness is noted in the arms or legs or difficulties are noted with the bladder, like not being able to control the bladder (or loss urine or bowel function). Acute LBP can be a very painful experience, but usually resolves quickly.
There are situations when the pain does not improve satisfactorily, which should then prompt comprehensive medical attention.
