I believe these are pretty common and usually harmless, most often associated with anxiety/stress.

I have had them fleetingly over the years from time to time, like a very fast fluttering in my neck, but the last few months they seem more frequent.

They are several times a day now, most often at work when I am moving fast, but also at rest and not in stressful situations.

I've ignored it up to this point, but wonder if I should get it evaluated just in case.
