Newly diagnosed 48 year old male diabetic with moderate hypertension. Was prescribed lisinopril 20mg daily and for a month & everything was fine. I had a pre-existing back problem that got much worse and I was at a loss as to why it flared up until I read carefully the package insert on lisinopril and noticed multiple musculoskeletal side-effects. Upon d/c'ing the lisinopril the symptoms abated and I was curious to see if anyone has had similar experiences. What made the causal connection so difficult was the very slow negative effects upon the back and the relative lack of info on this serious side-effect. Thanks!
