I am having some late radiation side effects with lesions that won’t heal. My treatment ended in August 2022. I recently started pentoxifylline 400 mg twice a day. I have read several articles that state the medication shows good results but it takes several months to see change. It somehow helps in the production of blood cells and it is suggested to take with vitamin E. My radiology oncologist has also suggested HBOT which increases oxygen levels which help with healing. I won’t begin to explain HBOT but it can easily be researched. I have requested a new prescription of StrataXRT but have not received it yet so cannot say if it works for later side effects. Hopefully it will help since I had such good luck with it protecting my skin during treatment. What is happening to you and what are you trying?
