answer:Right side is usually either appendix or gall bladder when it comes to organ pain, but since yours is just from a position, maybe it is muscular. It certainly doesn’t sound like it is appendix (usually lower right side). It could be gall bladder (right side behind the rib cage, but usually extremely painful when it is a severe attack) but it would be such a minor episode there would not be much to be done except maybe to lower your fat intake, which might be a good idea anyway. Your liver is over there, but I don’t see why that symptom would be your liver. Does it have any relationship to when you eat? It could just be a muscle cramp that comes and goes. Have you asked your doctor about it?
