I had my left carotid artery cleaned out on 8/31/2016. Due to right amodified radical mastectomy eiyh recstruction in 1990, it suggested NOT to have IV's or Blood Pressure on my right arm. so a Blood Pressure cuff was put on my left leg. After the carotid artery was done I felt both of my knees and legs were severly in pain and they been, now it's been 4 days and I continue sm in pain, leg swollen and still using a walker.
