i have been on lisinopril for a couple of years now and i started to have headaches everyday. i talked to my doctor and he gave me a month of benecar to try. the headaches eventually started to fade and the pain in my joints, especially my feet and back, began to fade as well. i ran out of benecar and had some lisinopril left over from my last refill. i have been taking the lisinopril for a week now, and the foot and back pain have come back. any connections?
