My fiance is a 34 year old male and has been to the ER 3 times in the past few weeks. He has kidney stones. However, he is continuing to pass blood in his urine and lots of blood in his stools . He continually has left flank pain down into his groin, and vomits very frequently. The pain gets worse then a little less for a few days but, the vomiting never lets up. Today he s been in a great deal of pain and his urine is very dark brown. Is this another kidney stone or something else?
