Has anyone heard of TTX for nerve pain? It's being tested in Canada. There was a small piece about this on a TV show.
This is from blowfish or the puffer fish. A lot of what I read states for cancer pain but the TV show also stated nerve pain, along with some research when I searched this online, it mentions nerve pain also.

The man they interviewed was pleased with the results, he was taking part in a trial study for nerve pain.

Thought I'd share it with you all in case you haven't heard about it.

It does have risks but again it's only in the trial phases.
