I have noticed that I'm getting this re-occuring pulsing in the right side of my neck approximately half way up. I do not have pain and it does not feel swollen but I've noticed it happening more and more. I do take a beta blocker for a heart condition I had approximately 10 years ago (tachycardia). As I said, I have no pain and my heart rate is not elevated when this happens, it just pulses and "pumps" and then quits.
