@ededed Yes! I mentioned this to my gastro and he was supportive. I sent him the link to the hospital where my daughter works. They have hyperbaric as part of their wound care department. I notice that my Medicare Advantage requires physician prior authorization, but since Medicare approves it, this should be workable. I'm one of those people who normally needs more intense treatment than average. Guys in my Ancan support group were surprised that my gastro called radiation proctitis "permanent," then admitted that after eleven and seventeen years since radiation, they were still having occasional symptoms. I'm stubborn enough to keep trying to find better healing options.
