Could i have got a hiatal hernia from the stomach flu? threw up harder than ever then a week after ended up in er with breathing trouble+chest pains..

Hiatal hermia: Stranger things have happened. But i guess it could develop if you were coughing so hard. Usually it is a chronic problem that is associated with reflux and if breathing problems occur that means it is very big and needs surgery to be fixed.

Hiatal hernia: That is a possibility. It is also possible that you already had a small hiatal hernia and that the vomiting has increased the size of the hernia and/or caused your stomach to slide up into your chest. It would be best to get evaluated by a gastroenterologist for an egd and ugi.
