I feel like I have water in my ear. had the same symptoms about a year ago..went through all the exams, all negative..couldn't figure out what was causing the 'sensation'. Dr suggested Using Flonase, and it cleared it up. Now I have the same on the other ear. Should I be concerned? I am 2 years post treatment (35 rads, 7 cisplatin) for throat cancer. At 2 year check in January was NED.
