experiencing calf, foot, and hand cramping. 1st time about a month ago when taking terazosin and phenazopyridine. After the 5th night of nearly hourly calf & foot cramp attacks lasting 5 to 10 minutes, I suspended the terazosin. No more cramps. My urologist gave me Rapaflo instead and I ve been on that for 8 nights. Today, minor cramps in my hands and feet kept threatening to get worse but if I rubbed the affected area, the distorted, almost semi=paralysis would dissipate. My urologist was puzzled by this reaction. Any ideas ?
