I have a lump in my throat, making it hard to swallow. It started late last night and just came out of nowhere. It doesn't really hurt that bad and my throat isn't sore, but the lump keeps activating my gag reflex and making me sick to my stomach. I keep throwing up. Other than this I seem to be fine, except for a little bit of a post nasal drip. Do you know what is causing this and how to get rid of it? The lump seems to be getting bigger and harder and is where the Adam's apple would be. I am a 21 year old female, if that helps. Thank you
