Disc bulges and facet hypertrophy are signs of degenerative changes in your lumbar spine.
As the intervertebral disc dries out (it is mostly comprised of water content), it becomes more brittle and can crack/tear the outer covering and the disc material can bulge or herniate outwards and place pressure on adjacent nerve roots.
The facet joints are like hinges at the back of the spine and assist in movement. Facet hypertrophy occurs when the degenerative process causes cartilage to break down in the facet joints and the bones can rub together causing friction. There can be development of bone spurs that can also cause compression of the spinal nerve roots.
Degenerative changes are a normal process of the wear and tear on our spines as we age. The pain and sensory changes occur from the friction of the bones rubbing against each other and any contributing nerve compression that results.
Your doctor can review the findings of the MRI in greater detail and explore the available treatment options. Many times conservative therapy with anti-inflammatory medications and physical therapy will relieve the symptoms. If conservative therapy does not help, additional treatment methods such as epidural steroid injections or facet joint injections may be considered.
