Cold finger symptoms and conditions

been taking Altace for about 1 year. never experience the terribl3e cough i hear so much about. however do have the following with a 2.5mg. feeling of throat closing or jammed, very cold feet at times, lightheadedness all the time. i also take Toprol xl 25mg so the combo could make it even more so. all my tests come out normal, so it has to be this medicine. i guess you either have to live with it or go through a trial and error period with other medication.
