Hello, since tomorrow when i go to brush and when i brush my tounge, some green and bitter vomit comes. Happening since 2 days. Except it i am not having any issue with passing of stool or stomachache etc. Vomit also comes when i force not on its own. But due to its colour i am worried. What to do. I also have some pain in upper middle chest, dont know whether it is linked to same problem or what. Please guide.
