There is no fastest way to get relief from lying back pain and any treatment will take some time. The causes of lying back pain can be spondylolisthesis, herniated lumbar discs and osteoporosis. Physical therapy, medication and surgery can be used depending on the specific cause. 1. Ankylosing spondylitis: Ankylosing spondylitis is a chronic immune disease that causes a lot of damage to the spine, leading to lower back pain and limited movement. Non-steroidal anti-inflammatory drugs such as celecoxib and ibuprofen can be used to relieve pain. If medication is not effective, surgery can be chosen. 2. Lumbar disc herniation: The protruding nucleus pulposus of the intervertebral disc will irritate the neighboring nerve roots, especially the ventral nerve, which will lead to lumbar and leg pain. Physical therapy, such as traction, can be used to relieve the pain. In severe cases, surgical treatment can be chosen, such as spinal endoscopic intervertebral nucleus pulposus removal. 3. Osteoporosis: the lumbar spine is the part of the human body that is most likely to bear weight, and when osteoporosis occurs in the lumbar region, the vulnerability of the lumbar bones will increase, and the lumbar spine is prone to minor fractures, which can cause lumbar pain. These patients can be treated with medication, such as calcium carbonate, calcium lactate, vitamin D. Physical therapy, such as sunbathing and ultraviolet light, can also be used. If the symptoms of low back pain persist, seek medical treatment.
