Upper back muscle strain involves the overstretching or tearing of muscles in the thoracic region, often caused by poor posture, sudden movements, or heavy lifting. Lower back muscle strain, on the other hand, occurs when the muscles in the lumbar region are stretched or torn, typically due to improper lifting techniques, sudden twisting motions, or prolonged sitting in a poorly supportive chair. Both conditions can result in localized pain, stiffness, and limited range of motion.

Therapeutic products for upper and lower back muscle strains often include heat pads or cold packs to alleviate pain and reduce inflammation. Additionally, lumbar support cushions are commonly used to provide proper spinal alignment and support, aiding in the recovery and prevention of further strain on the back muscles. These products, combined with gentle stretching exercises, contribute to the effective management and relief of discomfort associated with upper and lower back muscle strains.
