You can most definetly have kidney problems with that back pain. My father and I both suffer with kidney stones. He has a cronic problem where he has been having surgeries after surgeries for 40 years. I have had nine stones myself. The pain in your back could possibly be the stones moving or you may have infection. You need to see a uroligist on a regular bases. If you know that any other members of you family have had kidney stones you need to tell you doctor. Kidney stones are very hereditary. If you have pain in the pelvic area it is a stone moving to be passed or it may be stuck. It is a pain worst then labor. Make your doctor listen or see another doctor. Kidney stones can cause damage and you can loss a kidney.
