high blood pressure
"I have been on Linsinopril 5mg for about 2 years, it does the job to bring down my BP readings but much below the normal range, and I have had serious headaches during these times the kind headaches that I have never experienced before.  It's just horrible, I can not function normal daily life anymore.  I thought to stop take this medicine but the doctors say that I have to be on it to control proteins in my urine.  I am feeling miserable."
