Right side rib pain towards back and up to sholder blade could this be gallbladder problems. Pain gets worse as day goes on?

Ultrasound. A pain usually worse with eating or late in day after big meal could be gallstones.
Possibly. Generally gallbladder pain occurs under your ribs on the right not over them. Also, it tends to occur after you eat (particularly greasy foods). It would be unusual for gallbladder pain to get worse throughout the day. However, gallbladder problems can act very different from patient to patient. Your doctor should be able to sort this out with you.
