So the official diagnosis from the MRI is disc trouble. The disc is squishing outward and pressing on the spinal cord. The doc recommends a steroid injection. That is supposed to help enough that it can recover on its own. If that doesn't work, the fix would be surgery. Spinal fusion, I guess. The only good thing about that is that it's the lowest vertebra. The injection sounds painful. I've got to wait six weeks. I've got a week's worth of pills in the meantime. :-(
