Hi, I had a very sharp pain on the right side, under my rib cage when I bent down to pick something up, as soon as I stood up and rubbed my side, I immediately felt like I was going to vomit, and had to rush to restroom, then I felt like I dry heaved but nothing came up except some saliva? It seems ok for now, except a tiny slight pain, however, I m wondering what might this be and if I should be worried? I don t feel like vomiting anymore.
