I would say the same thing, which is to wait it out and see if you get any improvement in the next few days. Did he prescribe any pain medication? You may want to get some of that too to help with the pain temporarily.
It sounds like you have a cracked tooth. Your tooth is traumatized from the drilling. I would give it a couple of days to see if it calms down, ask the Dentist to use a tooth sluth to check each cusp for a crack. goodluck
