Low left shoulder and high right shoulder are generally caused by poor posture, scoliosis, frozen shoulder, lumbar disc herniation, etc. The treatment includes conservative treatment and surgery, and different treatments are adopted for different causes. 1. Poor posture: developing adolescents who carry shoulder bags for a long time, overweight school bags or incorrect sitting and standing postures will lead to high and low shoulders, so they should avoid carrying shoulder bags, maintain good sitting and standing postures, and improve their high and low shoulders by correcting their postures. 2. Scoliosis: There are congenital and acquired factors for scoliosis, and congenital factors are usually treated by surgery or wearing a brace, while acquired factors include long-term sleeping and sitting postures, trauma, etc. Generally, conservative treatments are taken first, and scoliosis can be corrected through exercise, while severe scoliosis requires surgery. 3. Frozen shoulder: Frozen shoulder will lead to local muscle adhesion and pulling muscle tissue, at the same time, the patient will also avoid exercise due to unilateral shoulder pain leading to muscle atrophy, which will lead to high and low shoulder in the long run. You can take celecoxib, ibuprofen capsules and other drugs to reduce inflammation and analgesia, at the same time, the patient should carry out functional exercise of the affected shoulder joint, if conservative treatment is ineffective, minimally invasive joint surgery. 4. Herniated lumbar intervertebral disc: after the herniated lumbar intervertebral disc compresses the nerve root, the patient will have a protective posture to alleviate the symptoms of nerve root irritation, which will lead to scoliosis, and at the same time, the compression of the nerve root will lead to pain or spasm of the muscles on one side of the spine for a long period of time and also result in scoliosis, which will lead to the emergence of the high and low shoulder. Surgery can be performed to relieve the nerve root compression. There may also be other reasons for the low left shoulder and high right shoulder, so it is recommended to go to the hospital in time to clarify the cause of the disease, and to treat the cause of the disease. The above drugs are recommended to be used under the guidance of a doctor.
