I had a small ear infection about 5 months ago. Although my ear remains to feel 'full' and I have pulsitle tinnitus in the effected ear.
I have seen two ENT, and there is nothing visually wrong with my ear. No discharge or anything. It doesn't even look red.
I have associated facial pain, which maybe linked to the C1 joints in my neck - which is in the process of being treated. Although my Dr's can't understand why my ear would still be feeling full, and why I have the tinnitus.
I have had a MRI and CT .. just general brain ones .. and they both showed up fine.
