How do i ease the pain of throwing up my stomach lining until i get to the doctor?

Need to find cause#1: It all depends on what's causing your to throw up your stomach lining .That's a very unusual finding, and would need to be seen by a doctor sooner than later. You should not delay in being seen, as the pain alone would be too much to bear, and you don't want it to be something serious that may mean you have to go to the er to be treated.
