I had similar damage from radiation. My treatments completed May 5th, 2023. At my 1st follow-up appt in Aug, I told my radiologist that they gave me perpetual strep. throat. I had 35 doses over a 7-week period.
I was told to give it time. By Nov. 2023 I was better. Pain not so bad but still had a hard time swallowing and food did not taste like much. It is mid Jan. and swallowing is still difficult compared to my old normal, but pain is gone.
I am at 7 months, cancer free so far, 43lbs lighter, don't like to eat as much as I used to. I can live with this.
I am told I can expect more improvement over time. 1 -2 years? I will keep updating. Hope i can keep the weight off. All this said from the days of struggling to get 8oz of boost down (took me oxy and an hour) to now, I have improved immensly and I hope you have similar results.
