I thought I had food poisoning - started with a headache - few hours later thought I was experiencing acid reflux. I took some anti acid chewable and the pain in my upper abdomen persisted. The pain intensified as the time went on. After 5 hours I finally threw up which relieved the pain I was having in my stomach. Went to the doctor he had blood drawn to run tests. He said the liver readings show a slight elevation but was not going to make a determination until he received sonograms results
