High Blood Pressure
"This medicine was added because Atenolol alone was not controlling the borderline high blood pressure.  I didn&#039;t have much side effects at first, but now I can&#039;t walk a block with getting very painful leg cramps.  My doctor told me to quit taking it until he can run blood tests.  I have been drinking lots of water, which was supposed to help with the cramping, but has not relieved it."
