Stenosis

Stenosis refers to the narrowing of a passage or opening within the body, most commonly in the spinal canal or blood vessels. This narrowing can restrict the flow of blood, nerves, or other fluids, leading to symptoms like pain, numbness, weakness, or limited movement. For example, spinal stenosis narrows the spaces around spinal nerves, causing compression and discomfort. The condition can develop gradually due to aging, injury, or wear-and-tear, and treatment options vary from physical therapy to surgical intervention, depending on severity and impact on quality of life.
