Kòm ou ap vin pi gran, disk ou ap vin pi gran avèk ou. Epi, san patipri inevitableman, yo kòmanse bonjan. nwayo a sèch soti ak olye pou yo gaye chay la pou respire, pèmèt tèt nan presyon yo devlope nan disk la. ka zo kase minit ka parèt nan sifas la nan vètebral la, ak evantyèlman mennen nan twou ti, ak nwayo a pouse moute nan vèrtèbr nan tèt li. twou sa yo rele nœuds Schmorl a. Fant nan bag la deyò fibrou pèmèt nwayo a enteryè nan herniate nan, kreye sa k souvan li te ye kòm yon "disk glise". essayant sa yo ka peze sou nè epinyè, ak se konsa li a pa etone ke sa a ka fè mal.

As you get older, your discs get older with you. And, fairly inevitably, they start to degenerate. The nucleus dries out and instead of spreading the load so evenly, allows peaks of pressure to develop in the disc. Minute fractures can appear in the surface of the vertebrae, and eventually lead to small pits, with the nucleus pushing up into the vertebra itself. These pits are called Schmorl’s nodes. Cracks in the outer fibrous ring allow the inner nucleus to herniate through, creating what’s commonly known as a “slipped disc”. Such protrusions can press on spinal nerves, and so it’s not surprising that this can be painful.
