Hello, I need to ask you about swelling in my feet and ankles. I am 65 years old, female, on two doses of lisinipril, with duretic twice a day. My feet have been swellin for several years. The doctor said it is because I am so heavy. My feet have begun to really bother me. they feel really tight and hurt nearly all the time. I am also diabetic, but my sugar is in normal range. I take metformin twice a day.
