How long has it worked for?

I googled the procedure and it seems like it's an injection of "anesthetic" to a nerve in the neck. Is that what you're talking about?

Yes it is . The procedure wasn't really painful just uncomfortable and took about 20 minutes.

I did it about 3 months ago I can't recall exactly.

I was able to find a head and neck doctor that agreed to do it and did it for about 800$.

60 minutes made an episode about it that's when I first knew I had to try it

There are 3 sites that they generally target but I just did right C6 .

Do you plan on repeating it?

You generally repeat it if your symptoms come back .

If it does then ya for sure
