Bloodletting therapy for lumbar muscle strain has no scientific basis, and improper operations can easily cause infections. Therefore, this method is not recommended. Lumbar muscle strain is primarily caused by poor posture and chronic strain, leading to symptoms such as back pain and limited mobility. The main treatment for lumbar muscle strain involves rest and developing correct habits for using the back. Non-steroidal anti-inflammatory pain relief medications can be used in combination to alleviate pain. Other treatment methods such as heat application, physical therapy, massage, or trigger point injections can also be adopted. Generally, these methods can effectively relieve symptoms. (Specific medications should be used under the guidance of a physician.)
