My stomach is hurting me but only when i lay down or go on my side. with that, i feel the urge to puke but when i go to the bathroom nothing comes up.

Abdominal pain: If your symptoms have just started this could be the onset of a viral gastroenteritis or food poisoning with diarrhea to follow. However if abdominal discomfort is worsening with associated abdominal tenderness I recommend an examination by a physician. Otherwise try drinking flat room temperature ginger ale to relieve nausea. Follow a light diet starting with some broth and some saltine crackers.
