Could Blood In Urine Be Due To Micro Haematuria?

HI, my name is Lisa. I had a cystoscopy done on 3/16/15 by a urologist and was cleared of mesh erosion ( transvaganal mesh), kidney stones, bladder stones and cancer. I was informed I have micro hematuria/benine. Because I m still having severe pain in my back and I still have blood in my urine do you think a second opinon would be a good idea? I ve been having major issue s with this Transvaganal Mesh since it was placed in 2011
