I was put on Lisinopril (10 mg) back in August for my diabetes. My blood pressure is very normal without medication. About a month or so later I developed a urinary tract infection, something I have never had before, which was followed by severe, migraine-like headaches along with sinus pressure around my eyes. I also felt very anemic. My doctor(s) attributed the headaches to a degenerative disc in my neck. After five weeks of these daily headache bouts, I stopped the Lisinopril when my chiropractor insisted it was the blood pressure medication that was causing the headaches. The headaches subsided within a week.
