Symptoms of lumbago are pain in the loins or lower back, also known as the lumbar region, explains Dictionary.com. Depending on the cause of lumbago, the symptoms include muscle weakness and numbness, states the National Institute of Neurological Disorders and Stroke.
Lumbago, or lower back pain, has multiple causes, from strains, herniated discs and traumatic injuries to sciatica and spinal stenosis, says the National Institute of Neurological Disorders and Stroke. Some uncommon causes are kidney stones, infections and tumors. Rapid weight gain and pregnancy can also cause both temporary and chronic back pain. When nerves become compressed or pinched, lumbago can result, as seen in sciatica. If this medical condition is the culprit, the individual usually experiences shooting pains down one leg and muscle weakness as well.
In rare circumstances, tumors and cysts can compress the sciatic nerve, according to the National Institute of Neurological Disorders and Stroke. Herniated discs, spondylolisthesis and spinal stenosis all occur when the spinal column somehow becomes disrupted. Herniated discs rupture or bulge out of place, which then puts pressure on nerves. The latter two conditions occur when the spinal column itself slips or narrows, also compressing the nerves.
An individual with lumbago has several treatment options, explains the National Institute of Neurological Disorders and Stroke. Other than treating the underlying problem, the individual can heat and ice the area to reduce inflammation, do strengthening exercises, take certain medications and undergo spinal manipulation and other therapies.
