I have an odd thing with pain, and, the best way I know how to describe it is that, I do not feel pain when I should most of the time. Sometimes I do feel it, but it doesn't feel like pain, more like a really bad itch, or a washed out version of what I think pain should feel like almost like I am disconnected from the event. Sometimes I feel it but only awhile after I should. I've often wondered what causes something like this?
