While playing football today, I tripped when I took an extra leap in an attempt to gain more yards. As a result, I feel internal pain right the middle of my chest area. I also feel an uncomfortable in my lower respiratory tract when I noticed a change in my voice. I suspect it being mucus blocking my larynx. Even though it has been about six hours since I fell, I have noticed the chest pain when deep breathing about three hours prior. Please help me examine my incident. Thank you.
