I have been on Lisinopril for about 10 years and it has been working for me just fine. For some reason over the past two months my bp has been up much higher than normal. My doctor says it's not stroke level and he want to wait and see if it's going to go back down after another month and then decide what to do about it. I'm also getting headaches everyday which is not normal for me. It really makes me feel uncomfortable. Other than having Hep C, anxiety and some depression, my health is ok. I've been stressed about a few things but it's never caused my bp to go up and stay up before. Any ideas?
