Ear clogged and hearing problems

i have had ear clogged issues for over two years. i hear myself speaking like i am in a tunnel similar to airplane ears. i have had eustation tube swelling all this time and also have gone through ballooning of my tubes, sinuses and septum. all with no results. i am now taking allergy shots for seven months. Still no improvement. Can someone help me with more info?

Have you had an MRI? Sounds like Patulous EDT.
