hi,
i have experienced the "lump" in the throat feeling. it felt like it moved! but now i have the feeling like blockage in my throat when i swallow, you know like it goes down slow. i dont really have the sore throat, but an uncomfortable feeling on the right side of my throat sometimes. you should try slippery elm. it soothes sore throats. you can get it at your local health food store. and also braggs apple cider vinegar is to help with heartburn. dont take alot at one time though because it gave me an upset stomach. so slippery elm for ypur throat, apple cider vinegar for the heartburn.
