I have had that a handful of times over the past couple years, i dont really think its anything to worry about if it goes away after a few seconds, if it continues to hurt i guess see a doctor but im not a doctor anyway so dont take my word for it... i dont think that logically anything could be totally wrong unless it continued to hurt. i think its just a severe cough, try to avoid that if you can, take smaller hits cuz it hurts like fuck.
