Why would my doctor refer me to a vascular surgeon if my ABI is normal
Recently I saw my primary care doctor about pain in my legs and feet. He did an ABI which was normal and also an ultrasound on my legs to check for blood clots. No evidence of blood clots. I have never smoked and I do not have high cholesterol. I am not diabetic. I called to ask why he referred me and the nurse said because my knee was swollen and I had complained of foot pain. What is he looking for?
