question: My mother in law has been complaining of back spasms off and on for the past several weeks. A urine culture was taken which was negative for UTI and bladder infection. The MD told her she had kidney stones and prescribed antibiotics. She felt better for a while, but the spasms are still coming and going. Now she is also experiencing dizziness with nausea/mild vomiting and more frequent than normal stools. Are there specifies tests we should request be done in order to get to the bottom of this.
