Newbie to This Forum but Not Tinnitus

Hi all,
This looks a great site to share views. I have had high pitched T since early twenty's (now 54) now have low frequency hum morse code intermittent T since 2011 following a bout of Eustacian Tube Dysfunction following the flu. It comes a go's but mostly comes! Been looking at various causes but can't seem to conclude anything yet. Looks like it isn't going anywhere after 3 years of annoyance. Nobody who has not had this understands, so its nice to read about others suffering the same blight.
