I had a fear of needles until I was 7 and got another shot that DIDNT hurt...after crying for a half an hour, while waiting.
I still remember the doc stepping on my toe to distract me from the shots!
By the age of 7, I was a pro. Had so many earaches as a kid that the doctor had to come to the house, and give me penicillin shots in my butt. We didn't have a car. I'm talking about 1951. Finally had my tonsils and adenoids out at age 5. They used ether back then. No more earaches. And we lived through the series of three Polio vaccinations that left your arm in pain for hours, to the point that you couldn't even lift it. That was the worst vaccine I ever had. Needles don't bother me, other than novocaine. I don't mind the needle. It's the hours of numbness afterwards I can't stand. So whenever I've had bridge work done, a tooth filled, etc., I don't take novocaine. By the time the novocaine takes effect, the dentist's work could already be done.
