Chronic pain that doesn't respond to standard treatment often sends providers looking for new tools to add to their practice.
Neural therapy training teaches licensed providers how to give low-dose numbing shots known as neural therapy injections. This includes skin bumps, scar shots, deep shots, and some nerve cluster shots. This guide covers the basics of neural therapy injections, safety rules for neural therapy providers, and how neural therapy training works alongside regenerative injection therapy.
What Is Neural Therapy?
Neural therapy uses low-dose numbing shots, usually procaine, at set body spots to help with long-term pain. These shots do not numb pain like normal shots. The goal is to reach a spot linked to nerve problems. Neural therapy injections sit within the wider field of regenerative injection therapy.
Neural therapy began in Germany in the 1920s. Doctors Ferdinand and Walter Huneke created it. Some call it "Huneke Therapy." Today, neural therapy providers around the world use this method as part of their practice.
What Causes This Effect?
The idea is that procaine changes the electrical state of local tissue. This may affect nerve signals. This idea comes from theory, not proven science. Old injuries or scars may leave tissue in a changed state. This may send bad signals through the body. This can cause pain far from the first spot. Neural therapy training teaches providers how to test this idea safely.
What Does Procaine Do?
Procaine, given in low doses (0.5%–1%), may calm the tissue. This may help normal nerve function. This effect is called the Huneke phenomenon. It means fast symptom relief after a shot. This relief can happen far from the shot site. Neural therapy providers use this as one clue, but it is not foolproof.
What Is an "Interference Field" (Störfeld)?
An interference field, or Störfeld, is an old damaged spot; often a scar, injury, or infection. It may send bad signals to other body parts. Störfeld means "trouble spot" in German. Finding these spots is a core part of neural therapy training.
Common spots include:
Surgery scars (belly, C-section, dental)
Tooth issues (root canals, wisdom teeth)
Tonsils (repeat infections)
Old injuries (breaks, whiplash)
Sinus or ear infections
How Do Providers Find One?
Neural therapy providers use patient history, a body check, and a test shot. They inject the spot in question. Then they check if symptoms change elsewhere. This step is unique to neural therapy injections. It does not replace normal testing.
What Conditions Is Neural Therapy Used or Studied For?
Neural therapy providers use this method for long-term muscle and joint pain, scar issues, and some nerve problems. Proof differs by case.
Neural therapy sits under regenerative injection therapy. Providers often pair neural therapy injections with prolotherapy, trigger point shots, or acupuncture; all common tools within regenerative injection therapy.
What Injection Techniques Are Taught in Neural Therapy Training?
Neural therapy training covers four methods: skin bumps (quaddeln), scar shots, deep shots, and nerve cluster shots. Each method reaches a different depth. Providers need hands-on practice in all four before giving neural therapy injections on their own.
What Is the Quaddeln Technique?
Quaddeln means giving a tiny shot just under the skin to form a small bump. The needle goes in at a low angle. It gives 0.1–0.2 mL of procaine. Neural therapy providers use this to map nerve paths first.
How Is Scar Infiltration Done?
Scar infiltration means giving neural therapy injections into and around a scar in a grid pattern. Small amounts (0.1–0.5 mL) go at the edges and through the scar. A fast symptom change elsewhere hints the scar was a trouble spot. This is a guess, not a fixed test.
What Is Deep Segmental Therapy?
Deep segmental therapy targets tissue below the skin: joints, ligaments, and spine-area tissue. This matches the spine level tied to the symptom. Shots use more fluid (0.5–2 mL) and go deeper than quad-dels. This technique is a key part of advanced neural therapy training.
What Are Ganglion Blocks?
Ganglion blocks target nerve clusters, mostly the stellate and sphenopalatine ganglia. These are the hardest neural therapy injections to learn. They sit near big blood vessels.
Stellate ganglion block: Targets the neck nerve chain at C6–C7. Used for arm, neck, and head pain.
Sphenopalatine ganglion block: Targets a nerve cluster behind the nose. Used for migraine and face pain.
Both need close watch during neural therapy training.
How Do Practitioners Ensure Safety?
Neural therapy providers stay safe by using clear landmarks, checking for blood first, giving small doses, and using ultrasound when they can.
Find bone and vessel landmarks first
Pull back the plunger before each shot
Go slow, using small amounts near vessels
Use the shortest needle needed
Use ultrasound for deep or nerve shots
The riskiest spots are neck arteries and veins, plus small nerve gaps in the face. These are studied on models or cadavers during neural therapy training, before real patients.
What Equipment and Injectables Are Required?
Neural therapy injections need a small set of tools: numbing drugs, thin needles, and normal syringes. Procaine is the top pick.
Procaine is the top pick for neural therapy injections. It works fast, clears fast, and is gentler on the heart than lidocaine, which stays in the body longer.
Who Is Eligible to Take Neural Therapy Training?
Neural therapy training is open to licensed providers who can already give shots: MDs, DOs, NDs, PAs, APRNs, and chiropractors where allowed.
Active license in good standing
Shot skill (trigger point or joint shots)
Current CPR/BLS card
Proof of scope for the shot depth taught
Learn Neural Therapy checks license and scope at sign-up before any provider joins its neural therapy training program.
What Is the Learning Curve for Neural Therapy Training?
Learning neural therapy takes both class study and hands-on work, built across levels.
Level 1: Nerve basics, skin and scar shots
Level 2: Deep shots, safety rules
Level 3: Nerve cluster shots, under watch
Ongoing: Case review and guided practice
This staged path helps future neural therapy providers build real skill with real neural therapy injections, step by step.
What Are the Certification and Billing Rules?
Neural therapy training ends with a certificate. Billing often uses trigger point or nerve block codes. No single U.S. board certifies neural therapy. Legal use depends on your license and training record.
Log the shot site, drug, amount, and response each visit. Billing often uses CPT codes 20552, 20553, or the 64400 series. Check with a billing expert first. Get signed consent before treatment. List key risks in that form.
Why Train with Learn Neural Therapy?
Learn Neural Therapy offers hands-on neural therapy training for licensed providers who want to add these skills safely. The program mixes class study with real practice in all four core methods of neural therapy injections. License checks are built into sign-up, so every provider who joins is ready to practice regenerative injection therapy the right way.
