Parasym — tVNS Device

I would put it in the "inconclusive" category.
It seemed to help at first, but then I became unsure as time went on.

Honestly, it is worth a try since we all respond differently.
Tinnitus behaves very eratically and there seems to be no rhyme or reason to it, therefore it is hard to pin down if something is helping or not.

 

I stopped this treatment as it spiked my tinnitus and it didn't calm down in two weeks of use. I fear the timing is essential, playing music randomly while stimulating the vagus nerve didn't help me at all. I'm locked in a three months rental contract now but at least it was worth a shot.

 

The Parasym treatment that I did included their accompanying sound file. I believe that Parasym states that both the vagus nerve stimulation and the sound therapy are required for effective treatment.

 

It spiked mine, too, at first, but then it settled down and by the time I finished the 90 days of treatment it was an overall dramatic reduction of tinnitus symptoms for me.

 

Effectiveness of transcutaneous vagus nerve stimulation for the treatment of tinnitus: an interventional prospective controlled study

 

I think this is the conference where they explain the results:

Konferencja dla Pacjentów Szumami...

It's in Polish, but subtitles with automatic translation works quite well.
