What Causes Cramps In The Legs After Passing A Kidney Stone?

I passed a kidney stone a couple of weeks ago and began to experience cramps in the calves of my legs. They sometimes became knotted and very painful and further problematic because I walked when the the condition was acute. I consulted a physician and he had a series of blood draws which were inconclusive. Today, I saw another doctor on a different matter and shared my problem. He recommended that I try Repinirole. The pain is concentrated to the lower half of the calves and is primarily manifest in soreness that is painful when moving. Please give me your assessment.
