See answer. If kidney stone is in your right kidney and if question is whether kidney stone is the cause of your described pain, the answer is "possibly" if no other valid cause of your pain has been established. That said, a 5 mm renal stone in a young adult has the potential to cause problems at some point, and certainly not unreasonable to recommend eswl treatment regardless of whether it is symptomatic.
