Wow. This is quite a lot, and I'm really sorry you had to go through all of this.
I had a similar experience two years back, it was a first too. After being given the anesthesia, I still felt pain. It could best be described as shock waves 😂.
Me I didn't allow them continue o, I'd rather be on drugs than feel shock waves that doesn't only affects your teeth, but even the brain.
I'm glad you feel much better.
Success in your forthcoming test also ✌🏿.
