Most of these types of injections I've seen and discussed with many doctors have 2 components. Short acting local plus a steriod component. The local should bring very fast relief and only last a few hours at best. The steriod might not kick in for a couple of days, then may last many days or longer.
In my case, both worked well, but with the increased functionalty brings increased activity and the possibility of setting myself back. (I think this is pretty predictable in most people. It's difficult or impossible to stay in jail when the door is open!)
R your facets bad on MRI? I don't know if the pattern of relief can be from steriods injected during the ablation? increased pain from incomplete ablation? Again... I'm just thinking out loud here and could be completely off base. Let me know what you think.
