Sorry to hear about your condition. I've been dealing with chronic throat inflammation and trouble swallowing and it can be very uncomfortable. Transitioned to mostly raw plant based diet which has helped a lot. Also a 22-day juice fast, although I see fasting doesn't feel good for you. Definitely check out Dr. Morse videos on youtube, he probably spoke about your issue in some of his lectures.
What I've found though is that the most efficient way to get through something and heal is to deal with it on an energetic level, to see what stuck emotions are causing the illness and then releasing them. Just now listening the "Letting go: The pathway of surrender" audiobook by David Hawkins and it's eye opening. Some other tools that could help are Ho'oponopono (book Zero limits) or EFT tapping.
