Hi, I am struggling with unexplained intermittent flank pain on the right side, when there is no pain I constantly feel dull and discomfort along with numbness and tingling on the right flank area. Following are my questions. 1) What doctor should I see? General physician , Gastroenterologist, orthopedic, surgeon? 2) I have seen a couple of doctors in the past and none of them is able to determine the cause of the flank pain, can anyone tell me what is the cause of this pain ? I have IBS and cervical spondylosis. But not sure of the reason behind flank pain, please assist.
