I have had left flank pain for 5 months and blood in my urine.  The pain is a constant dull ache, but will increase in intensity to severe renal colic pain lasting 3 or 4 days. I have had a history of kidney stones, but there is no obstruction noted.  I have had a complete work up to rule out other conditions-GI, GYN, and Ortho.  I have recently found an article on loin-pain hematuria.  Should I bring this to my doctors attention?  Should I seek expertise from another urologist?  My urologist says there is nothing wrong with me.
