question: I have had constant pain in lower right abdomen area for the past three months - the pain varies from tolerable to intolerable and depends upon stress and other factors I do not know b.c. i do  experience the pain when I am in a low-stress environment. Please also note that I look tired all the time even if I get sleep [pronounced dark circles].  Everyone always tells me I look like crap even if I feel ok at that moment [i.e. the pain is dull or at a tolerable level -mild discomfort is the best it gets]. I have had the following images taken: 1) CT 2) ultrasound.  I have had blood work and urine work done more than once.  The images show two kidney stones in right side.  But, the urologist is CERTAIN that the stones are NOT causing my pain, but he does not know why I have this pain, the source of this pain or how I got this pain.  The urologist referred me to the Gastro doctor - we did blood work and urine - ultrasound - took the RX Prilosec ---reviewed the CT -- Gastro says everything [all anatomy depicted in the full abdominal ultrasound] is fine and that he does NOT know why I have this pain - Gastro says next step is to look inside stomach or do a endoscopy on both ends but that he says highly highly unlikely that the endo will shed any light on this right side abdominal pain that is definitely NOT muscular or tied to my obliques.    So, here I am, still with this pain and left without answers.  I am going for yet another opinion and peak next week at a Cedars Sinai Gastro.  Please, any ideas what this pain is due to and why I have it, what it is etc? Also, what should I do at this point.  Again, assume urologist is correct in that my stones are NOT at this point lodged in a manner to cause the lower-right ab pain I speak of.  WHAT IS THIS?????? Thank you in advance.
