I'm 21 years old and i don't smoke or drink and i'm not overweight. Recently i have been having these strange stomach pulsations in the upper right quadrant of my abdomen, and i am pretty sure it's not synchronous with my heart, it's kinda like something is randomly poking at my stomach from the inside in that area, and it bothers me when i'm trying to get to sleep, i haven't really experienced any stomach pain, maybe some mild pain in my lower stomach, but nothing serious, anyone have any ideas what this could be?
