If the pain is due to a sprain of the lower back, first rest and braking, then local cold compresses, and after 24-48 hours, local hot compresses and topical spray of Yunnan Baiyao can be applied. If the symptoms of sprain are serious and the activity is limited, it is best to go to the orthopedic department of the hospital in time to do a CT or MRI examination of the lumbar area to clearly check whether there is a fracture or a herniated disc. If there is a problem, further therapeutic intervention is needed under the guidance of a doctor. Generally, in case of fracture, absolute bed rest is needed for more than 1 month, and then gradual rehabilitation training will take about 3 months to recover. In case of lumbar disc herniation, conservative treatment such as bed rest, physiotherapy and traction of the lumbar region can be considered for mild symptoms, or minimally invasive surgery for severe cases.
