I've been in pain for 5 months on my upper right abdo just below my ribs could this be something to do with wheat or gluten intolerance ?

Maybe: This would more likely reflect a problem with your gall bladder. Wheat or gluten intolerance can be totally asymptomatic, produce nonspecific Irritable bowel syndrome (alternating normal to loose stools 3 d/wk), or a handful of other symptoms including cramping. Wright down a history of your symptoms and any interventions you have tried and take this to your doc.
