i have seen everyone getting worried about this but, i've had this since i was very young all the way at about ten and i've been dealing with this for about 16 years now as i am 26 it's nothing to dangerous to my knowledge since i'm sure it would have caused issues sooner but the one fix i have found for this is drink something warm slowly and try your best not to become to anxious about it and when you are relaxed and not caring about it, you will find it goes away at least to the point it is not bothering you cause i have noticed that the more anxiety you have that causes your throat to tighten makes it worse along with acid reflux makes it really bothersome.

i do hope this helps calm some who are worried about this and please don't take everything i say as the true fix to this but this is what i have found that fixes mine when it shows up or becomes problematic for a few days
