I ve been taking losartan 50mg for about year. I decided not to take it, for about 8days now because i was feeling neck and shoulder pain and cramping in my legs at night while i sleep. I m checking my blood pressure almost everyday. What puzzles me is that my pulse fluctuates from 40-76 in a few minutes. I ve been told that I have irregular heart beats. That has never gone away while and after I stopped the meds. I do not take anything else right now. What say you?
