Should I be worried?

Hi i have been having sore throats every night for a few months. Its always on my right side and my ear on the same side is a little sore. I've felt around my throat and I can't feel anything odd. I have alot of gastro issues. I have been diagnosed coeliac since my teens (im in my 30s now), but now they seem to think I have colitis. Not sure if I've done damage to my throat through vomiting or I'm just feeling a little drained. Nightmare trying to get through to doctors. Is this something I should be bringing up with gp dont want to be a bother if its nothing?
