Symptoms of spinal stenosis(or narrowing) closely resembles to that of disc herniation, yet are not likely to be caused by traumatic injury. In the case of spinal stenosis, the pain is caused when the gradual degeneration of bones, ligament, and intervertebral disc eventually compress the spinal canal.
Aside from the cases of congenital spinal stenosis, the condition usually develops in the 40s and the incidence rate is highest among the 50s. The major distinction between spinal stenosis and lumbar disc herniation is that the motion of bending at the waist will trigger acute pain for those with the latter condition, while the pain is alleviated for those with the former condition.
- Pain when back is straighten or while walking
- Brief alleviation of pain while walking by sitting down, only to be returned when walking is resumed
- Gradual decrease in walking distance due to pain (500m→300m→100m→50m..)
- Lower back pains and aches
- Tingling/numbness, pain, or stiffness in sacrum, thighs, shins, or ends of feet
- Thinning or weakening of leg muscles
- Frequent night cramps in calves
- Development of bone spurs in the lumbar(lower back) region due to degeneration, causing compression of the nerves
- Stenosis resulting from spondylolisthesis
- Swollen muscles or ligament, from inflammation in the spinal canal region, causing compression of the nerves
- Post-surgical ligament or muscle adhesion (detection requires thorough examination)
