So at work earlier I hit my stomach on a corner, & it hurt pretty bad for such a little run in. But since I hit it it's been in none stop pain. I've tried to take a warm bath, lay in different positions; nothing seems to work. I also keep throwing up. But I went pee & there isn't any blood.. Any ideas on what's wrong or what I should do?
