I have throbbing pain mainly on the left side of my neck which I have had for months, but it is now more regular (daily). Today, I started to feel it slightly on my right side. I am 52 years old (female) not overweight (135 lbs - 5 4 ). My blood pressure has been slightly elevated over the last few months. I have a slight heart murmur and I do experience palputations with shortness of breath. I am thinking of contacting a Cardiologist, but not used to running to doctors. Could this be my carotid arteries? Thank you.
