Why do some people not feel pain?

Mary  asked the Naked Scientists:
   
I have a serious question about my apparent ability to not feel pain, particularly pain after a surgery.
 
About ten years ago, I had a lumpectomy on one breast. I never needed any pain medication after surgery. Ten days later, I had both breasts removed because of numerous cancer sites discovered on the previous surgery. I never need pain medication of any sort.
 
About ten days ago, I had orthoscopic surgery on my knee. I have not needed any pain medication since that surgery.
 
I also discovered a long time ago that if a had something like a headache, I could literally turn off the pain.
 
My question is: Is this unique? To what can I attribute this to?
 
Mary        

What do you think?

Some people are apparently capable of self hypnosis to the extent they can have surgery without anesthetic ...

Some people may carry changes in the genes that control the pain-sensing nerve fibres that convey noxious sensations to the brain.

Geoff Woods, a Cambridge-based scientist, discovered a gene called SCN9a without which some people are incapable of feeling pain:

More recently he's also shown that there is more than one form of the gene in the population and that certain forms of it may cause carriers to experience more pain than others:
