Ok so today I went to my friends house we hung out and did stuff then her little sister(age7) started acting really FUNNY like we almost couldn't stop laughing our butts off ! Then my friend grabbed my arms and said hey" i can throw you over me! so first I then grabbed her arms and pushed her down first(in her house) then she feel right on me then she yanked me up and threw me this time.Then we both screamed a couple of times then I noticed i weird feeling in my chest.When her mom and my mom got back I told them and they said that feeling was my Esophagus.Then after I came back home and ate dinner I ran/walked my neighborhood 2 times with/my/dog then when I ran i could feel my Esophagus hurting again and I'm only 13! What could be the problem? Has this ever happened to anyone?
