There is a bubbly feeling below my right rib cage. my doctor had me examined through kub ultrasound and was diagnosed as having bilaterally non-obstructing renal micrlithiases. i have no period for 3 months. are they somehow connected?

I can think of no way to connect your symptoms. Your body is trying to talk to you. Take notes and share with your Dr.

The KUB showed small stones in your kidneys. I would not thing this should not be preventing you from having a normal period. The first question I would ask, "Could you be pregnant" and have a test taken to answer this, before proceeding to further evaluation.
