Does pain or excitement trigger an episode for you?

I went snowboarding today (was supposed to go yesterday when it wasn't icy) and I'm in a lot of pain. I don't know what I did to my left shoulder, but I fell down pretty hard on the ice a couple of times, and my shoulder hurts a lot... like A LOT a lot. Slammed it! Probably because I'm rusty.

But what's interesting is that I haven't gone snowboarding at all this season, and I think the anticipation and excitement are definitely pulling my mood "up"... and the pain might be adding to it too. (Maybe my brain is overwhelmed?) Haven't been sleeping, not tired, energetic... the whole package deal. Been like this for a few days, but I'm irritable, not euphoric.

What about you?
