Looking for a gentle, drug-free solution to chronic pain or nerve irritation? Perineural Dextrose Injection Therapy offers a safe and effective option.
The foundation of this treatment lies in the scientific understanding of how certain peripheral nerves can become hypersensitive following injury, overuse, or inflammation. When these nerves are irritated, they can continuously send pain signals to the brain, even after the original injury has healed, resulting in chronic or persistent discomfort. This heightened nerve sensitivity can also contribute to inflammation in the surrounding tissues, further aggravating pain and slowing recovery.
Perineural injections work by delivering a carefully formulated dextrose solution directly to the affected nerves. This approach serves two main purposes: first, it helps calm the overactive nerve fibers, reducing their sensitivity and interrupting the cycle of pain signaling; second, it works to decrease inflammation in the surrounding tissues, creating a healthier environment for healing. Over time, this targeted treatment not only alleviates pain but also supports the body’s natural repair processes, allowing for improved function, mobility, and overall quality of life.
Aesthetics21 describes perineural injections as a non-invasive method to target and relieve nerve pain directly at its source—without surgery or steroids.
Clinically, patients often report near-immediate easing of pain—sometimes within hours—thanks to targeted nerve modulation rather than systemic medication.
This approach relies solely on dextrose solution without relying on pharmaceuticals, narcotics, or anti-inflammatory medications. There are no reported dependence or systemic side effects.
Looking beyond Aesthetics21, broader medical literature and pain clinics typically recommend PIT for patients with:
While Aesthetics21 provides a concise overview, clinical literature and expert sources fill in more specific details on technique, experience, and recovery.
Patient Preparation
The procedure is performed in-office, without need for general anesthesia.
Injection Technique
A small, very short needle (similar to a TB test) is used to deliver a few milliliters of 5% buffered dextrose solution just beneath the skin along the course of the target nerve.
Session Frequency & Course
Typical course consists of 3–6 treatments, spaced 1–3 weeks apart depending on severity and nerve complexity.
Mechanism of Action
The injected dextrose is thought to calm overactive, inflamed nerves, interrupting maladaptive pain signaling and reducing neurogenic inflammation (mediated by substances like NGF, substance P, and CGRP).
Perineural injections are used to manage a wide range of pain-related and nerve-sensitivity conditions. These may include neuropathy, fibromyalgia, migraines, muscle tension, and other disorders involving irritated or inflamed peripheral nerves.
This treatment involves delivering a specialized solution—often containing local anesthetics, mild anti-inflammatories, or other therapeutic agents—directly around affected nerve pathways. By calming irritated nerves and interrupting the transmission of pain signals, perineural injections help reduce discomfort, ease muscle tension, and support the body’s natural healing response.
Your healthcare provider will first identify the precise nerves or areas to be treated, often using palpation or imaging for accuracy. A very fine needle is then used to administer the solution just beneath the skin. The process is generally quick, well-tolerated, and involves minimal discomfort—many patients describe only a brief pinching or pressure sensation.
The timeline for relief varies. Some patients experience improvement almost immediately after treatment, while others may notice benefits gradually over the next few days. In many cases, a series of treatments leads to longer-lasting pain reduction and improved mobility.
