I am a healthy 27year old male (5'11 160lbs), perfect blood pressure, good cbc blood count, etc. I went to ENT today because thought i had a swollen lymph node on the right side of neck. The ENT told me it was my Carotid Artery, the control 'something something' to the brain (i dont remember what he said exactly). I then asked him if it was normal, he said yea and mines was slightly bigger and it was most likely due to genetics and there's absolutely nothing to worry about. Well as soon as I get home I google, and now my fears are Carotid Artery Disease, which leads to stroke. Should I continue to worry about this and seek an appointment with cardiologist?
