I was laughing to hard and as I gasped for air and swallowed at the same time. (I’m certain the air went to my stomach because I burped extremely loud and long twice and continued to need to burp several hours after that without drinking anything or eating anything before and after this happened.) when the air went down it felt like my stomach was stretched shortly after there was a pain that cani can only describe as if there was some sort of large cut in my stomach and throughly my flesh accompanied by a warm almost burning sensation. Everyone is telling me I’m over reacting but it has 21 hours and there is still pain. Is it possible that the air could have ruptured or damaged my stomach. I’m deeply concerned for my a few of my friends have said I probably pulled a muscle in my stomach. Please help me I need to know if I need medical attention.
