Sandy23,
I have radiation fibrosis in several areas, but I’m no expert. I have looked into the subject, and found they say there is really no cure for it, just supportive care. A former rehab doctor at Memoria Sloan Kettering, Dr Stubblefield, is an expert in this area and is now in NJ, at Kessler Institute for Rehabilitation Care, so I missed seeing him in NYC.
Most recommend rehabilitation care. I assume SLP does exercises that may help as I’ve been through it several times.
For swallowing, I’ve had throat stretches by my stomach doctor (my mind is starting to fade) wheby they stretch your throat under sedation, usually when they do a yearly biopsy for barrets esphogus it has helped my swallowing.
There are a few books on the subject, one by Dr Stubblefied, and many arrticles on the subject such as this one:
