For any person trying to learn the causes of lower back pain, it is important to recognize first that it is not a condition but rather a sign of irregularities in the muscles, ligaments, and nerves in the lower area of the back and possible diseases found in that specific area, like the kidneys.
Lower back pain is commonly one-sided; depending upon the pinched nerve root, it may occur on the left side or the right side.
Because many conditions could generate the pain, cited here are the primary causes of lower back pain:
- Poor form, particularly when carrying large items (the mere act of carrying an object larger than your body weight could cause lower back pain). Sitting for a long-period of time with arch back can also cause pain on your lower back. If you work 8 hours a day in work office, sitting the whole time is inevitable. Take a break, stand up and stretch your back at least every three hours, and make sure that you are sitting up straight. Bad sitting posture can not be corrected by trying harder, you need to stop sitting badly and let your body resume its natural posture.
- Stress and fractures.
- Non-specific anxiety or sprain of the back muscles, ligaments and soft tissues.
- Physical factors such as disc degeneration in spondylosis, stenosis of the spinal, disc herniation, spinal abnormalities such as scoliosis, and leg length discrepancy (one leg is shorter than the other)
- Inflammation related illnesses, such as rheumatoid arthritis and spondylitis.
- Infections, like osteomyelitis, epidural abscess and Post-herpetic neuralgia, bring about nerve irritation.
- Metabolic problems, such as osteoporosis and osteomalacia.
- Cancers of the bone and spine that would constrict upon the nerves.
- Related soreness, such as in kidney disease and prostate cancer.
- Pinched nerve, which is appropriately called as nerve root impingement (direct irritation on a nerve) or nerve root syndromes, such as sciatica and cauda equina syndrome.
- Standard pregnancy (the rising weight and the strain of lugging a child causes strain on the lower part of the back, nerve irritation, and elongating of pelvic ligaments).
- Bone and joint pain syndromes, such as fibromyalgia (described by generalized ache, tenderness, rigidity and fatigue) and myofascial pain (with pain and tenderness experienced in localized areas referred to as "trigger points", which observes the dermatomal or radiating pattern of a peripheral nerve).
Depression has also been mentioned as one of the causes of lower back pain. However, reports on patients suffering from the pain and making use of anti-depressants as remedy have generated inconclusive outcomes.
