I havent lost my voice before but I do know of a girl in WA that lost her voice too for 6 months and she had the burning, I forget what they did but I think they massaged they voice box area and also gave her ketamine lossanges. I did loose the ability to swallow for 5 months, I had an ultrasound too my ganglion nerve and the vibrations shorted it out so I needed a feeding tube for the time and also could hold up my head. It took 3 months of a speech therepist coming too my bed every day to help retrain my swallowing.

You might want to find a speech therepist that knows something about RSD and see what they would reccomend. The speech therepist that helped me really understood infact she had RSD too from getter her tonsels out.
