"Is the joint usable within a few hours of treatment in anybody's experience?"

Is the joint usable now? When I had the shots for trigger finger it took 2 days before I started feeling no benefits and after 3 days it felt just fine and after the initial prick of the needle I felt no additional pain. The thumb joint was a completely different matter, the initial injection was very painful and after the lidocaine wore off, included as a painkiller,about an hour later there was pain from the medicine putting pressure on the joint which subsided as the day wore on and then things were good after 2-3 days. Good luck.
