hi Louise - whilst searching for mention of silence as the cause on the TRT site I found this about the fullness:
I am 32 years old, I have tinnitus and often get feeling of pressure in the ear (one or other) which causes me more of a problem than the tinnitus itself. One doctor said I had Eustachian tube problems, another said it might be Ménière's disease. My hearing is normal and I don't have any vertigo. What might this be?
This could easily be due to Tensor Tympani syndrome. The original article on this condition is available in the download area (as it is now out of print). A small muscle in the middle ear is attached to the ear-drum via the malleus bone. The muscle contracts normally if the face is touched, or air is blown on the eyeball. It seems to be equivalent to the blink reflex for the eye, but now no longer useful as a protective reflex for the ear. The appendix is an example of another body part that has lost its use due to time passing. Nevertheless the muscle often does contract if we are tense and reactive (perhaps due to increased autonomic activity in tinnitus or misophonia). Sometimes it can 'flutter' like having an insect in the ear, or give a feeling of drawing the eardrum inwards (which it does!). While the symptoms can be worrying and distracting, contraction of this muscle is harmless, and a common occurrence in the general population. Worrying about it makes it worse, just like tinnitus! The symptoms always improve as the tinnitus or misophonia improves following TRT, or simply with reassurance. Eustachian tube dysfunction, common in children, is very rare in adults nowadays. It can be excluded by a simple test (impedance eudiometry). Ménière's syndrome is also very uncommon compared to tinnitus and misophonia on their own, and is often wrongly diagnosed.
