tension and anxiety can cause pain

I woke up just before 4am virtually pain free, and that is a good thing, but my mind plays a kind of game with me. because at the same time you have to get used to pain, you have to get used to not having it also and thats the hard bit. I may psychologically create a pain where there is just a twinge, because the anticipation of pain causes tension and anxiety which then may result in pain. I have for the last 3 years had contant pain, never being able to trust my body to not give me pain on every move I have made, so we will see how today goes will it be pain free or not that depends on how I think and cope with trusting my body, so we'll see.
