I agree with CMatthews. I received a shot in the ankle to deal with tendonitis back in the day. I remember thinking the pain would be alot worse.
The Dr. injected the tendon area. When I thought the shot was over, I looked down at my ankle. He disassembled the needle from the syringe (needle still stuck in tendon!). He then attached the syringe with the cortisone and injected it. Turns out the first shot was to numb the area.
My thought now is, I wonder if he was trying to save money by using only 1 needle or if he had depleted his supply of needles earlier in the day.
Or maybe this is just a Wyoming thing.
