Greetings, I have a herniated disc that makes a small bulge into the nerve in my lower back. I've read that the bulge can be removed by discectomy, but that the herniation doesn't heal. What prevents the disc from healing? I'm not medically trained, so pardon my ignorance, but shouldn't the herniation close eventually and scar? Is the lack of healing due to the material the disc is made of? If so, what is that material/tissue? If it's not able to do this, couldn't someone make an adhesive to put in the tear or tape that can be placed over the tear to keep it closed? Sorry if this sounds inane, but this thing is driving me crazy and so it's leading me to all sorts of schemes. John
