I have been on Lisinopril for about 3 years now. My BP has been at around 120-130 over 80-90 while on it. A few weeks ago I started getting a ringing in my left ear. About a week ago I started waking up with nose bleeds. Well, I thought that was due to allergies. I have nose bleeds a lot and have since I was a little one. Well, I have a lot of stress at work and I would get headaches by the end of the day. I just wrote it off as anxiety and stress since I have been diagnosed with anxiety and depression. Well, normally (before I was on Lisinopril) I would take my blood pressure like 3 times a week or more. I hadn't taken it in about 2 months. I took it this afternoon and it was 152 over 103. Is my medication not working anymore? Is this normal (not the BP, but meds not working)?
