It Started Tuesday Night When I Was Eating Pain In

It started Tuesday night when I was eating pain in upper stomach like i was full or something was stuck. Thursday I was throwing up all day and night. It was a burning sensation not only when I was vomited but all the time. This vomit lasted until Friday afternoon. I still have burning and uncomfortable feeling in my stomach. I been eating hello pudding yogurt but nothing seems to help. I have been diagnosed with a hernia couple of years ago. I sometimes have shortness of breath and feel a little week. Any suggestions what I should do?p
