Pain specialists deal with the hardest cases: patients who have tried everything and still hurt.
Medications stop working. Steroid injections wear off. Surgery is not always an option. And the patient is still sitting in your office in pain.
That is exactly where perineural injection training comes in. It is one of the most useful skills a pain specialist can add in 2026. It works best where other treatments fall short.
What Is Perineural Injection Training?
Perineural injection therapy is a simple technique. You inject a low-concentration dextrose solution, usually 5%, just under the skin. You do this along the path of a painful nerve.
No imaging needed. No sedation. No hospital setting.
Here is the idea behind it: injured nerves release harmful substances. These substances stop muscles, tendons, and ligaments from healing properly. This creates a cycle of ongoing inflammation and pain. Dextrose breaks that cycle. It blocks those substances and interrupts pain signals at the nerve level.
This is not a painkiller. It targets the reason the nerve is firing in the first place.
Does the Evidence Back It Up?
Yes; and it keeps growing.
The strongest clinical data right now is for nerve entrapment conditions like carpal tunnel syndrome and ulnar nerve entrapment. Multiple trials have shown that dextrose perineural injections work better than saline. At follow-up, they also outperform steroids.
Results are showing up beyond entrapment cases too. In one study, stroke patients with shoulder pain that was not responding to medication saw their average pain scores drop from 7.3 to 1.0, with no side effects reported.
Conditions that respond well include frozen shoulder, migraines, sciatica, carpal tunnel syndrome, plantar fasciitis, tennis elbow, trigeminal neuralgia, and TMJ disorders.
That covers a large part of what pain specialists see every week.
Why Should Pain Specialists Care More Than Others?
Because you are already most of the way there.
You understand nerve anatomy. You know pain science. You have patients who come to you specifically because nothing else has worked. Perineural injection training does not ask you to start over. It builds directly on what you already know.
It is a simple office procedure. No imaging required. Physicians and other licensed healthcare professionals can do it. It also works well alongside biologics and other regenerative approaches.
That brings up an important point. Neural injection therapy pairs naturally with PRP, prolotherapy, and hydrodissection. So, if you already offer regenerative injection therapy, adding this fills the neurogenic pain gap those methods sometimes leave behind.
You are not replacing your current protocols. You are making them more complete.
What Happens During the Training?
A good perineural injection training course does more than teach you where to inject. It changes how you think about pain.
You learn the science behind how dextrose lowers nerve pain. You practice injection techniques for different areas of the body. You go through safety protocols. You also learn how to treat common conditions like neck pain, headaches, and upper extremity pain.
Most programs offer both online and in-person formats. The hands-on portion matters most. Practicing under supervision with real patients is where your confidence grows.
Many practitioners say they can use the technique with patients right after finishing the course. That kind of fast, direct application is rare in medical education.
Which Conditions Will You Be Able to Treat?
Here is a clear picture of what opens up after training:
Nerve entrapment pain; carpal tunnel, ulnar nerve, thoracic outlet
Chronic joint pain with a nerve component; shoulder, hip, knee
Headaches and facial pain; occipital neuralgia, trigeminal neuralgia, TMJ
Post-surgical pain; where nerves stay sensitive even after a successful procedure
Low back and pelvic pain with a nerve-related cause
Clinical research across these conditions continues to grow. More neural therapy providers are adopting the technique, and positive outcomes are being reported consistently.
Practice-Building Side of Things
There is also a straightforward business reality worth naming.
Patients with chronic nerve pain are long-term cases. They move from one provider to the next. When a specialist finally gives them lasting relief, those patients talk; and they send others.
Adding neural injection therapy to your practice sets you apart. Pairing it with regenerative injection therapy lets you offer something most clinics cannot. You can address both the structural and the nerve-related sides of pain in the same visit.
That combination is genuinely rare. In a competitive specialty, it makes a real difference.
Who Developed This Technique?
Dr. John Lyftogt, a physician from New Zealand, developed the technique. He created subcutaneous dextrose injections for nerve pain and has since taught the method to practitioners across more than ten countries.
Today, several trusted training providers offer structured programs. These include Learn Neural Therapy and Empire Medical Training. CME-accredited options are available with hands-on training led by board-certified pain management physicians.
The path to getting trained is clear. The barrier is much lower than most specialists expect.
Chronic pain patients need better options. Pain specialists need tools that actually work when everything else has failed.
Perineural injection training is one of the clearest answers to both of those problems in 2026. It is safe. The evidence supports it. It is easy to learn. And it fits directly into what you already do.
If nerve pain is part of your patient population, and it almost certainly is, this is the year to get trained.
If you are looking for a structured place to start, Learn Neural Therapy offers practitioner-focused courses built around exactly this technique, from the foundational science to hands-on clinical application. It is a practical next step for any specialist ready to expand what they can offer their patients.
Your patients have been waiting long enough.
