Does anyone else get this.

For years randomly I get a sudden feeling like the top of my throat suddenly feels like it is contract/fluttering, like i won't be able to take my next breath. It happens very rarely but the last few days it's happened twice which is unusual. I am relaxed when it happens usually. It isn't a palpitation it actually feels like it's my throat or tongue contracting or fluttering and I won't be able to breath but then within seconds it eases away. Then afterwards I do feel like my throat is tight, which I know happens with the fear.

Does anyone else get that sensation? Is it anxiety? I have always assumed it is. I don't panic when it hits, I kind of freeze and wait for it to pass but it is unnerving.
