Hello, I am a 20 year old female and have experienced a twitching sensation in what I believe is my right carotid artery, in my neck. I have felt it happen briefly 3 times today, and I m wondering if this is normal. I m not sure if it is related, but I additionally had about 5 days of bad acid reflux last week (which I ve never experienced before). No feeling of heartburn in my chest, just nausea and discomfort in my throat. Should I be concerned? Thanks.
