Lumbar distension and pain may be a symptom caused by degenerative changes in the bones of the lumbar spine, which can lead to lumbar disc herniation, lumbar spinal canal stenosis, osteoarthropathy, lumbar spondylolisthesis and other diseases. It may also be lumbar muscle strain. If the patient often stands, sits, bends and carries heavy objects, it will cause inflammation of the lumbar dorsal fascia and muscle strain. If you are a female patient, you should also consider whether it is the symptoms caused by menstruation. If it is a degenerative bone disease, it can be treated with non steroidal anti-inflammatory and analgesic drugs under the guidance of a doctor, and if necessary, it can also be treated by orthopedic surgery in the local hospital. If the symptoms are caused by lumbar muscle strain, hot towels can be used for hot compress, and massage, oral anti-inflammatory and analgesic drugs can be used for treatment.
