3 ent have said I don't know what to do with you! I need an answer.

Faces,

You described much of what I have had for a little over a year.  Feels really good in the morning upon waking, with little tinnitus and a pretty clear head.  Throughout the day it worsens, and in the afternoon it will get pretty bad and the congestion starts.  To me, the weather plays a role.  Two different ENTs, several different GPs, an audiologist, a TMJ expert have looked at me and I am fine medically so the internet searches that suggest tumors or really scary stuff are ruled out.  But, they don't know how to fix it.  I have a long history of ear problems and infections related to cleft palate and its repair decades ago, so those do not help the situation.  I did just get a referral to an allergist since that is worth a try, but I am doubtful that anything will be found.

I will say this about what I believe has worked, and is working for me, so maybe it will help you.  This stuff has slowly gotten better, although it can vary.  Diet can impact it and I cut out dairy and wheat for a while since the theory is that dairy and gluten thickens mucous.  I drink lots of water and have been trying to sleep more.  Basically, it's trying to thin the mucous and relieve the inflammation in your ears and your Eustachian tubes.  From what I have read, you feel better in the morning because your brain and nerves 'shrink' while you sleep and your sinuses and tubes also drain more.  This condition brings lots of stress and that works against your body.  Exercise helps much, as it helps the blood flow and at least makes me feel clearer in the head.  Yesterday afternoon, I was feeling pretty clogged and my ear was ringing and 'stiff'.  I did some weight lifting and it felt much better; so much so that the tinnitus was almost gone for the rest of the afternoon and evening.  These are things that I believe have really helped me, although there's certainly no guarantee.

I hope this helps.  I'd recommend a book by Dr. Robert Ivker called "The Sinus Solution" (I think), and some other books about natural methods.  I am not very holistic in my outlook, but it is clear to me that the medical community and its prescriptions cannot solve this problem.  Flonase only made me skittish.
