I often feel this weird gagging sensation at the back of my throat for no reason. It kinda feels like my throat muscles are pulling a little bit, like a slight gag if that makes sense. I do it a lot, usually when I'm not nauseous at all I will feel perfectly find but it starts and won't go away but I don't feel sick at all. Sometimes it makes me panic and sometimes it doesn't bother me because I know nothing is going to happen. Does anyone have any idea what I'm talking about? It happens at random and it's so annoying I want it to stop.
