I have mild spinal canal stenosis at L4-5 due to posterior annular bulging, accented be ligament hypertrophy. I also have left foraminal encroachment at L5-S1 due to fibrosis and disc protrusion. The doctor said he could fix the stenosis problem and it should take care of my pain. I have read that when a person sits, the pain gets better and even goes away. When I sit, I get more pressure, numbing toes, throbbing etc.
