<s>[INST] I am 81 and had a triple bypass about 7 years ago. My ankles and feet display tiny scattered blood vessels and recently, I developed itchy rash on both ankles. I was instructed to use pressure supports on both lower legs. Is this the right treatment? [/INST] Hi, Wearing a pressure support in legs is for preventing the clot formation in legs. This is important in older patients with a bypass who are prone to developed DVT. The small blood vessels which must be formed in legs are normal after a bypass because during bypass graft is taken from lower leg veins after which small vessels over front of leg dilate. These are normal. So don't worry and follow advice as per your doctor. Thanks Chat Doctor.  </s>
