My husband had stint's put in his heart 3 or 4 years ago. He was having some chest pains a little over a year ago and went back to his heart doctor. The doctor ran the scope to check to see if there was anymore blockage, at the time he also ran the scope down both of his legs. Now my husband is having severe leg cramps after walking or standing alot. He did not have this problem before the doctor ran the scope down his legs. why is this happening and is the anything that can be done?
