I'm starting HBOT soon (x40) to hope for relief from muscle fibrosis in my neck and a clavicular area as I was referred by my surgeon. It's the real deal 2.4 atmosphere type and they said two thirds of folks going in are for radiation injury now. It's an approved treatment for many things apparently. The way I see it there's several potential benefits besides any immediate relief of inflammation. It may help prevent further degradation, decrease hypoxia to rejuvenate cellular function and prevent reoccurrence. It could also boost lymph production. I'll post any results after it's over around 9/10/25.
