I am not looking for medical advice on the Internet I suppose just sensible opinion - I tend to be a worrier and I don’t want to go to a doctor if this is my imagination
DD2 is now 14 but always had issues with feeding when a baby. Hard to wind, a LOT of sickness and pain. Grew out of the reflux at about 1.
I have noticed since she was a small child that she sometimes coughs when she drinks - a gone down the wrong hole, small, tickle cough. As she’s never had any chest infections or any such like I haven’t thought much of it, but had wondered if a coordination thing like tipping in too much liquid from the cup, as it doesnt happen the same way with a straw. She also doesn’t/can’t burp.
Today I got cross with her because she confessed she had forgotten to drink anything all day (8 hours) and has a dry throat, and during the heated discussion about why this is bad for your kidneys, she said that it feels uncomfortable to swallow mouthfuls of liquid. She says it has always ‘hurt’ to do so. Which is news to me 
Now I know that she has had her throat looked at by GP’s multiple times over the years, also by the dentist. But perhaps this is further down and I am now all of the paranoid that I would be irresponsible not to get it checked out. But as it doesn’t seem to be causing any significant issues and could be a teenager being dramatic should I waste NHS time on it?
