Hi Laura,
I also had ear problems after radiation. Ears felt clogged/stuffed. Hearing was muffled. Clicking noises in ears all the time. ENT said it was due to effects of radiation on the eustachian tubes, which normally allow equalization of pressure. ENT installed a litte tubein each ear through my eardrum. It helped somewhat equalize the pressure and improved my hearing.

dx 2/13/06. modified radical neck dissection 3/9/06 multiple biopsies of upper airway and direct laryngoscopy. 1 of 47 lymph nodes positive for metastatic undifferentiated carcinoma (lymphoepithelioma). Unknown primary. Finished radiation 5/24/06.
