Lumbar curvature can be improved by general treatment such as rest, wearing a girdle, physical therapy, medication and surgery. 1. General treatment: rest, wearing a waist cuff, lying on a hard bed, and exercising the muscles of the lower back appropriately. 2. Physical therapy: local massage, traction, baking and other physical therapy can be taken. 3. Drug treatment: anti-inflammatory and pain relieving drugs such as ibuprofen and sodium rosoprofen, and neurotrophic drugs such as methylcobalamin can be used when accompanied by nerve damage. 4. Surgery: If the disease is long, conservative treatment is ineffective and the symptoms are severe, surgery can be adopted. It is recommended to go to the hospital in time to have regular treatment for straightening of lumbar curvature.
