Good morning, Merry Christmas good doctor, my exhusband just had vascular surgery for a blocked artery by his gorin and pryor to that he had a stent put in his right leg a week before. Surgery went fine, but he still insists that there is something else is wrong because his leg is very swollen, he does elevate his leg and does some walking not much because he say's it hurts him and his leg swells up more than usual, his leg is very swollen the skin is tight and now he is experiencing some pain......he is schedule for ultra sound at the end of the month which I will be taking him.....and because of that he things there is something else wrong so why order one he says...is he right or is it just a safety precaution to make sure nothing else is wrong.....
