Hi
@Mathew Gould
I suspect you may have seen the paper written by someone who solved his t using a neck brace? If not, you can read it here
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4803736/. We followed this line of enquiry, but found there is some controversy over the use of braces making the neck weaker. And if your neck muscles are already weak, which seems to be common in t from what I have read, then a physio may be reluctant to fit one for you.
However, it seems that in the reported case results were obtained very quickly, using the collar for very short periods of time, so you may be able to persuade a friendly physio if you make this clear. We thought it would be worth a try, as my son's t is very loud and pretty unchanging generally.
I also found Sarah Michiels at the University of Antwerp. She is a physio specialising in cervicogenic somatic tinnitus - see
https://www.uantwerpen.be/en/staff/sarah-michiels/ and uses general neck strengthening exercises to help t.
A PT local to you can give you similar exercises to do to help your neck.
Personally I would definitely do the PT to strengthen the neck. While you are there you could ask them if they'd be willing to fit a collar to see if it helps the t. If your neck feels wrong, then it seems like that should make sense.
But it sounds like things are going pretty well, with the tone reducing and disappearing? Do you not think you might be on the right track anyway with your chiropractic treatment?
Btw what country are you based in Mathew?
Kind regards
Shirley
