You probably do have a high pain tolerance. That is not the issue.
The part I highlighted makes me SO MAD!!
Your body was doing what it was made to do. The fact that the MD could not get his act together should not had an impact on your delivery.
If you could have delivered him at your own pace, in a calm quiet place,

with you telling people what you wanted

instead of them telling you what to do,

you might have a whole different perspective on this. It would have been a whole different event.
You got a good kid though!
now you all know one of my soapboxes
