This pain sounds musculoskeletal in nature. You should try some pain meds such as tylenol or ibuprofen for now. It the pain persists despite those medications, see you physicians then.
My father had chest pain for four days before he finally agreed to do to his doctor. When he got there they found that he had been suffering from a heart attack. They locked the doors and would not let him leave in anything but an ambulance. He is now thanking them for saving his life! Small or large any type of chest pain is worth getting checked out immediately. Not everyone falls over in extreme pain when suffering from a heart attack, and not everyone suffers the same symptoms. Like my father's heart attack, some can even last for days. I would recommened getting checked out immediately.
I wish you well.
