Most people who’ve heard of Stellate Ganglion Block (SGB) know it as a single injection near a bundle of nerves in the neck. Dual Sympathetic Reset (DSR) is a more refined version of that same idea — and it’s the protocol Dr. Ryan Wood has performed nearly 3,000 times to date.

DSR is an advanced SGB protocol that uses two precisely placed, image-guided injections at the stellate ganglion — the bundle of sympathetic nerves in the neck responsible for the body’s “fight-or-flight” response — rather than a single injection at one level.
