Isordil opens the arteries, and getting a headache as side effect is "normal" However, I think you should see a heart specialist if you had an abnormal ECG test or get an ECG done if the doctor did not do it yet. You may have angina. See http://www.nhlbi.nih.gov/health/dci/Diseases/Angina/Angina_WhatIs.html
