I have rapid pulse rate, feel heart beat in chest, pounding headache, swelling in ankles from new blood pressure medication, been taking 10 days (amlodipine 10mg). Also taking third course of prednisone for hoarseness from cough due to allergies and 2 previous BP medications (lisinipril 20mg, losartan 25mg) with side effect of dry cough. I can t tell anymore what side effects of the meds are causing what anymore.
