I am 50 year old female, 5 5 and about 180lbs. I recently (about a month) have the sensation of an air bubble stuck in my throat just below my collar bone. It happens randomly including while I am eating. Sometimes it is a gas bubble that comes out as a tiny burp. Other times not, just dissipates on its own. And, there are times that it feels like something just violently sucked an air bubble out of me in that same area. There has been no pain associated with this, just 6 or 7 (1 to 10 scale) pressure discomfort.
