Why your Lower Back Hurts
In todays post we will focus on: The Anatomy of your Lower Back
Your lower back consists of five lumbar vertebrae, the sacrum, coccyx, and nearby pelvic bones, forming a stable yet flexible base. These bones are supported by muscles, ligaments, and fascia.
Strains affect muscles or tendons, which attach muscles to bones. They happen when these tissues are overstretched or torn, such as during heavy lifting, sudden rapid movements, or repetitive activities like running. Symptoms include pain, cramping, muscle weakness, and tenderness.
Nerve roots from the lumbar and sacral spine extend to your legs, hips, pelvis, and feet, allowing sensation and motion. Because spinal discs sit close to these nerves, disc injuries such as herniation can sometimes cause irritation or compression, leading to pain, numbness, or weakness. Sciatica is one example.
