Positional and mechanical influences on the diaphragm.: If the pain is fleeting,you likely have pressure from your abdomen, on the diaphragm. You can decrease that pressure by eliminating carbonated drinks, excessive caffeine use, and increased water/fibrous foods, like raw fruits and vegetables. Particularly a dark green salad at night time Will help move stomach and intestinal contents while you're sleeping.Dinner should always be your lightest meal!
