Depends. Treatment depends upon your symptoms and where your true pathology is. You seem young to have symptoms of spinal stenosis, which is characterized by what you relate your problem is. Consrtvative care is the mainstay, so check with your doctor what is beat for you.
Depends on symptoms. If there are no symptoms, no treatment is needed. Ligamentum flavum is a strong yellow ligament that helps form the back wall of the spinal canal. It helps stabilize the spine. As one gets older, the ligament thickens (hypertrophy) and this can lead to pressure on nerves, or less space in the spinal canal. The facet joints in back of spine, can also have extra bone spurs pushing on nerves.
