Is it normal to experience concentration difficulties after a medical procedure that involves localised anaesthetic?

Because that's the only thing I can put it down to. If it isn't, I have no idea if I'll be able to write an essay or try to solve maths ever again.

Has lord gone mad aswell?

Could be. I felt pretty terrible after my dentist appointment.
