I was put on the blood pressure medication Norvasc 5mg almost 2 weeks ago.. After one week on the medicine, I began to have swelling in my my ankles, knees, and fingers, which I knew that was one of the side effects, but at the same time as the swelling began, I started having headaches every day... They last throughout the day. Usually by bedtime they have eased, and I do pretty good until the next morning after I have taken the medication.. Could the Norvasc be causing my headaches? I go back to the doctor in 9 more days, and I am wondering if I should try to deal with the headaches until my appointment... Also, would it be ok to take anything to help the headache? Thanks so much.
