A chemical so hot it destroys nerve endings – in a good way 8 years ago
Inject RTX, as it’s known, into an aching joint, and
it’ll actually destroy the nerve endings that signal
pain. Which means medicine could soon get a new tool
to help free us from the grasp of opioids.
Using a toxic capsaicin analog to destroy nerve endings sounds like an option (when taking to the inevitable extremes we are all dreading here), which could actually be worse than simply locking someone in a room so that they don't harm themselves or others with a different substance.
Reading this sounds like something out of a Shadowrun supplement, describing an intentionally horrifying prerequisite to some kind of cybernetic augmentation that renders your character a partially comatose brain in a vat.
