Moderate bilateral facet hypertrophy. Moderate right and mild to moderate left foraminal stenosis. Moderate right lateral recess encroachment, mild disc narrowing with vacuum change please tell me whats going on and what I need to make me stop feeling this way

### output:

HelloThanks for writing to ChatDoctorYou didn't mentioned type of surgery you underwent 3 and half years ago, any your MRI findings suggest that you have age related degenerative changes of spine in form of1.osteophytes measuring 2.2 mm. Osteophytes forms due to chronic strain on annulus fibrosis.2. You have herniation of intervertebral disc at L5-S1 level, and it migrates in inferior, cephalocaudal, anteroposterior and mediolateral direction. Herniated disc is causing mild to moderate left neural foramen narrowing and in right side it is moderately encroaching .3. Bilateral facet joints are also hypertrophied.4. Vacuum changes are also related to degenerative changes.5. Intervertebral disc is also mildly narrowed. Hope you have understood the terms. Get well soon. Take Care Chat Doctor.
