I have been taking lisinopril for more than 5 years now and just happened upon this site the other day. After reading all the posts I was amazed to see so many others describe the same side effects that I have had for years now, ie) pain in my chest and left arm that has led me to think I am having a heart attack. I have had 3 EKGs over the past several years and every time it was normal but the pain has persisted and to the point of not being able to sleep at night and constantly wondering if I am having a heart attack, it has been incredibly frustrating!!! So when I found this site I was very relieved to know that I am not alone here. I have also recently discovered a natural product that has helped many lower their BP, it is called Pro-Argi9 Plus, you can check it out at this link, ******, it could change your life as it has for many.
