sounds like you did something to make your brain focus on pain rather than nausea. It's not a healthy way of coping.
I know it's hard to think rationally when you are in a panic attack, but try to do something that distracts your brain another way - such as deep breathing, a cross word puzzle, playing the wii, listening to music, etc. It will help.
Self harming is never a good idea.
