high blood pressure
"I had taken Lisinopril for 5-6 years with no obvious side effects that caused me problems.  Until 2 years ago, one morning I woke with a very obvious, very swollen eye.  An ophthalmologist reported that I had gotten something in my eye and gave me eye drops.  About 2 weeks later, the same thing occurred with my eye more swollen.  I had an appointment with a new endocrinologist that day and decided to go to the ophthalmologist after that appointment.  On meeting the new doctor, he immediately requested my list of medications and diagnosed the Lisinopril as the cause."
