Patient: Hello. I am soon 68 years young. since some time I realize difficulties when walking and feeling like muscle cramps in the lower legs. I am on norvasc 5mg for about 2.5 years and on betaloc zok 50mg, and aspirin 100mg for 14 years.. also, i feel urinating becomes difficult especially at night when i have to go to toilet several times. without norvasc i didn’t have these problems.recent sleepless is adding to the problems. I did not see norvasc helping reducing my BP to normal.thank you very much!
