Hyperbaric Chamber Treatments

My husband who has radiation cystitis from radiation for locally advanced prostate cancer is trying to have hyperbaric oxygen chamber treatments (HYBOT) to help with the healing and pain. They were unsuccessful in reaching 2 atmospheres of pressure at his first HYBOT session because of a hemorhage in one ear and severe pain. An ENT put one ear tube to help equalize the pressure. At his next treatment they were able to bring him down to a lower pressure but this caused pain in the other ear. He had a second tube put in. At the next treatment he got severe pain over his left eye. A sinus CT showed a retention cyst in his left frontal sinus. Will he ever be able to get to 2 atmospheres pressure with this retention? What else can you offer about HYBOT?
