I battled different types of pain for a lot of years and did all sorts of things.....I have also felt major pain, alarming events.....You know you are there when you are ready to go to the hospital and request being knocked out. I ignored pain for years, but this is truly different.

Its hard to define pain, different types of pain, this website is a layman neuro site that explains the nuts and bolts of it all and answers some of our pain questions.

During my skiing I figure that I experienced (SIA) Stress induced analgesia. Psychological factors that activate endogenous pain control. (from within ourselves)

This can also play a part in our daily lives....funny how pain can come and go sometimes living with scoliosis.
