I had alwasy felt the worst pain I had ever experienced, was the local during a dentist appointment. A "local" into the old boys, is quite a bit more painful, as is a cut made as the local wears off on those same boys.
There usually is one side that is a bit harder to find, or isolate during the procedure, and this is where it will wear off on.
I used ice, and athletic suppoert for the first two days, and then just tightey whities for about two weeks, I would say about a week after the procedure I was walking about like normal, the grin pain on both sides is the worst part. 10-14 days, you will be your old self
