Unusual chest pain after longboarding?

I was longboarding (dont judge) and i was doing a pendi slide, one of the more difficult slides so to speak which involves twisting your body and forcing yourself to the opposite direction. After doing a number of these slides a started to feel a dull achy feeling in my middle rib cage area afterwards. I dont know what it is and im starting to worry about it. Anyone have an idea what it could be from?
