I know your post is from a long time ago Richard, but yes I have tried Reiki & it's definitely helped, but not yet cured. I have used it in conjunction with Bowen Therapy... the therapist for both is the same person.
She advertises & runs a business with her B.T. She does NOT advertise or push Reiki, I asked her if she knew who did Reiki on my 1st B.T. session with her & she answered that she did as an automatic response, not as an upsell of her abilities. I have had tinnitus for more than 5 years, when I 1st had it, it was at screaming levels, especially between 2am & 4am, it would wake me from sleep.
I saw a doctor about it, she suggested I take 5 days of Sudafed & use a nasal wash, that did help a little, at least to the point where where it didn't wake me in the wee hours most nights.
I then tried acupuncture... again, I had I got a little more relief.
Then I met my Bowen Therapist / Reiki Practitioner & I have been really WOWED by the results.
I went to her for a bad back believe it or not, & now my ears are way improved!
I have actually had some truly quiet times... only for a minute or 2... what a blessing!
Generally the tinnitus has way lowered in pitch, although it often ramps up around 3pm.
It's an ongoing process, my practitioner & I are hoping for a total cure, but if I don't get it, then I'm pretty happy with how I am feeling at the moment.
I have only been seeing this person for roughly 9 months & the difference she has made to me has been nothing short of amazing, I can live with my ears happily, my back is GREAT, I am feeling physically mentally, emotionally, spiritually healthy. It has been a process, & not cured in 1 or 2 goes.
I would recommend trying Reiki, & if you can find a therapist that combines Bowen & Reiki... well even better.
LUCK Carolyn
