Yes, my treatment was very similar. Never want to repeat it 😖. Grade 4 mucositus (?) in the mouth so swallowing medicine and water near impossible. Radiation burns with skinned blisters where underpants should be. Recovery was rapid a few weeks after finishing treatment. So: my advice? Be creative with dressings , use the creams for healing and topical pain relief. Accept all the help you can get. Australia is pretty good for these things, local Community Nurses are priceless. If you have a tough time, remember that there is an end date to it all.
