I'm asking this question anywhere there's a chance of getting a little advice, so please forgive me if you see it around the various oral cancer groups and pages. Is there *anything* I can do to prevent/slow/mitigate the formation of radiation fibrosis in my neck???

Over the last few weeks, my neck has been getting hard, the tissue is getting thicker; in the mornings it feels like concrete. I *do* have lymphedema (which is being treated), but this is *different* to the lymphedema. It's so horrible. Any advice very gratefully received.
