This doesn’t really fit here but I’m not sure where else to put it. Is there a difference between healing and regeneration? My cord is very fragile, atrophied they say. If when I fell I banged or bruised or stretched it—neurosurgeon says “dinged” it—rather than transected it, what is the potential for it to heal some? If it can, what would be the time frame for it to happen or not? Would it have made any difference to do steroids immediately? For how long might steroids still have an effect?
