Hello, I have been getting a sharp almost electric pain at the top of my stomach for quite some time now, and it comes and goes. It is very sharp and lasts about 15 seconds then goes away for about a day or so. I have a constant stomach pain, light almost unnoticeable, really really light nausea, but I cannot eat a full meal, I get full with half a hot dog. I mainly have pain in the lower left side of my stomach.
