Lumbar muscle strain is mostly caused by excessive activity, overexertion, fatigue, and intense exercise, which leads to the continuous pulling of the lumbar muscle fibers beyond their load capacity, resulting in injury. After the injury, many patients may not have sufficient rest, causing the muscle fibers in the lumbar region to become scarred, which is referred to as lumbar muscle strain. The primary symptoms of lumbar muscle strain are pain and limited mobility in the lumbar region, especially after intense exercise or exertion, with the pain gradually worsening and possibly radiating to the buttocks on both sides. The main treatment involves rest, which is the most important. Additionally, treatments such as physiotherapy, rehabilitation, massage, acupuncture, and oral medication can be used to aid in the recovery and growth of lumbar muscles, with the main symptoms being pain in the lumbar area and restricted movement.
