Thanks for all your posts about your progress (or lack of it) with tinnitus.
I'm curious to know, during all this time you've had tinnitus, have you ever considered whether an underlying infection could be involved? My tinnitus started last November after I returned from a snorkeling and free-diving trip. At first, I assumed it was due to barotrauma, but after extensive ENT examinations and scans revealed nothing, I tried steroids, acupuncture, and just about everything else I could think of. Eventually, I sent off blood tests for a Lyme-related infection—Bartonella henselae. The test came back positive, and it matched several other vague symptoms I had, such as shooting pain in the soles of my feet, superficial headaches that seemed to shift location, nightmares, and so on.
Lyme disease and its coinfections can also be linked to fungal or viral infections, often because of a compromised immune system and gut dysbiosis, so I haven't ruled those out yet. One of my students had an EBV infection around the time my tinnitus began, and I suspect that COVID or other viruses might be involved as well. There's no reliable way to know for sure, since antibody tests do not always indicate an active infection.
At the moment, I'm about five weeks into a course of antibiotics (Minocycline and Rifampicin) and herbal treatments. I'm working with Napier's in Scotland. So far, there has been little effect on either the symptoms or the tinnitus, though nothing has gotten worse. As you've likely experienced, much of this is a waiting game to see what helps.
