Hi so I recently got a cavity done today. When I was injected with the novacaine, I started experiencing some anxiety and my heart rate went up a bit. I do have a high level of anxiety in general but it was unusual for me because I've had cavities done before. Later into my day the novo and started to wear off about 3 hours later. Currently it's now 5:00 and my eyes Keep twitching almost every minute , feels kind of strange. Do you know if this is usual?

Could you explain to me everything please
