Why does my lower back feel a dragging pain?

The causes of aching pain with a sensation of heaviness in the lower back include: 1. **Lumbosacral muscle strain**: Prolonged poor posture or overuse of the lower back muscles can lead to muscle strain, resulting in a feeling of heaviness and pain. 2. **Lumbar spine disorders**: Conditions such as lumbar disc herniation, lumbar spinal stenosis, and lumbar spondylolisthesis may affect the stability of the lumbar spine, compress nerve roots, and cause aching pain with a sensation of downward pressure. 3. **Pelvic diseases**: In female patients, pelvic inflammatory disease and other pelvic conditions should also be considered, as inflammation may irritate tissues in the lower back, causing feelings of heaviness and pain. 4. **Urinary tract stones**: Stones in the urinary system, such as kidney stones, can also cause aching pain with a sensation of downward pressure in the lower back, especially when the stone is moving. 5. **Other factors**: Cold exposure, poor circulation, infections, and other factors may also cause aching pain with a sensation of downward pressure in the lower back.
