Sometimes I just get a real tight feeling like my throat is constricting, and also in my chest it will feel all tight, and I'll feel like I'm about to gag but I just hold my breath and freeze till the urge passes, and then I am usually okay, sometimes it happens several times but its never resulted in me getting sick. It just freaks me out. I dont know if this is just a sign of panic or what. Do others get this? Is it to do with anxiety or is there something wrong? I've never really had acid reflux problems, so I don't think its that.
