What Causes Sensation Of Fluid In The Ears And Head?
Otitis (ear inflammatio) vs TMJ disorder...
Detailed Answer:
Hi,
Fullness in the ear causes sensation of fluid in the ear / head. This is commonly seen in otititis media secondary to eustachian tube dysfunction. Since it more predominant at night post nasal drip is a possibility.
Besides ear conditions, I will also name temperomandibular joint (TMJ) dysfunction as a likely possibility since you hear a sound while chewing and biting teeth.
As your symptoms are subtle and many symptoms from aforementioned three conditions overlap with each other it will be extremely difficult to arrive at a conclusion. Therefore I will insist you see a physician for closer examination.
In the meanwhile please continue antihistamine medications. Start steam inhalation for added benefits.
Hope this helps.
