The duration of back pain depends on the underlying cause. Most cases of back pain resolve within a few weeks. However, some people may experience back pain for months or even years.
Acute back pain occurs suddenly and usually only lasts for a few days or weeks. This is the most common type of back pain. It is often caused by muscle or ligament strain, a bulging or ruptured disk, or osteoarthritis.
Subacute back pain may occur suddenly or gradually and may last between 4 and 12 weeks. This type of back pain is often more difficult to treat than acute back pain.
Chronic back pain occurs every day, may first appear quickly or slowly, and lasts for longer than 12 weeks. This type of back pain is often caused by degenerative changes in the spine, such as arthritis or osteoporosis. It can also be caused by chronic muscle tension, nerve damage, or certain medical conditions, such as fibromyalgia or inflammatory bowel disease.
If you have back pain that lasts longer than 2 weeks, it is important to see a doctor to rule out any underlying medical conditions and to get appropriate treatment.
