HI, my name is andy and i had a cooarctation of the aorta when i was three, i am now 16. I am on lisinopril and atenolol. lately, have always felt overheated and tired. i also, since on the meds lost all ambition(may just be age too). my feet especially, in my large, highly padded shoes sweat the worst. I am 6'1 and 160 lbs. i have also been light headed a lot, and have frequent chest pains. ne clues? is takin the meds a bad sign?
