hi, i have a question for you i sometimes have problems swallowing food. I would have this feeling as if the food is stuck in my throat and it would start to make me cough and gag as if i were choking. I don't know what could be wrong. On my right side of my neck it feels like there is a little lump but i been having that for a few years. Do you think that small lump on my right side of the neck could be causing me to have difficultly swallowing. I have also notice that there would be like a small red bump in the back of my throat but it would come and go. Do you know what that could be.
