Hello, I have a twitchy/pulsating artery in my left temple. I do not have any pain with it. Generally I am in good health. I am however, tired from a very busy life and do get breathless in the middle of the night when I am asleep. I am told that the latter is anxiety related. Therefore I am wondering if (or hoping that) perhaps this  twitchy artery is also stress related as I am in pretty good health. I also have other tics and shrugs - think I probably have a mild form of Tourettes  which manifests itself again when I am busy and have a lot going on.
Thank you for asking on Chat Doctor. In my opinion your twitchy/pulsating artery in the left temple with no other associated symptoms is not indicative of any disease process. It is a part of the physical symptoms of anxiety and stress that you are experiencing like breathlessness at night. You need to worry about the pulsating feelings of the artery and seek treatment for your anxiety. I hope this helps you.
