Hi, I recently had a TIA secondary to hypertension. I have never had leg cramps, but now I do walking long stretches. I am physically fit, and do not want this to effect my job. There are mornings that I wonder if I will make it to my office. I am on Norvasc, Lisinopril and Labetalol. Was taking HCTZ but stopped a week or two ago. My MD is sending me out a lab slip to check K and Mg, haven t had done as yet. But wondered if it could be side effects from my medicine.
