    The annulus is highly innervated with nociceptors (pain fibers). We know this from microscopic work and ill-performed discograms, a test used to determine pain generation capacity of the disc. With a normally performed discogram, the needle is placed in the center of the disc and fluid is forced into the nucleus of the disc to pressurize the annular walls looking for pain response. If however, the needle is accidentally placed in the annulus (which can happen if the discographer is not accurate with needle placement) there will be reliable lower back pain reproduced every time the annulus is pressurized. The pain fibers probably originate from the outside of the disc wall. Interestingly, if there is a tear of this wall, pain fibers grow into this tear along with blood vessels and sensitize the disc even more.

    This is what microdisectomy does not fix,right? The discogenic pain that arises due to the nucleus pressure or pressure received on annulus during any activity like running, jogging, biking, travelling in a car.

    It can only fix the pain which is associated with the outer layers of annulus which has got herniated by removing that portion of disc.

    Aberrant motion of the disc is what a microdiscectomy will not fix. The disc is designed to restrict motion, like a bushing. With annular tears, the disc motion initially increases and the disc moves in ways that increase the stress on the more intact but injured annular fibers. This leads to further damage. In many discs, this motion continues to destroy the disc wall and endplates, eventually leading to isolated disc resorption (https://neckandback.com/conditions/isolated-disc-resorption-lumbar-spine-idr/).
