Neural & Perineural Injection Therapy in Costa Rica: Natural Pain Relief Without Surgery
Chronic pain is one of the most debilitating conditions affecting quality of life — and one of the most undertreated. Millions of people live with persistent musculoskeletal pain, nerve inflammation, and functional limitations, often cycling through medications that mask symptoms without addressing the underlying cause.
At Rejuvilife in Escazú, Costa Rica, Neural Therapy and Perineural Injection Therapy offer a minimally invasive, non-surgical path to meaningful and lasting pain relief — by addressing the neurological root of chronic pain rather than simply suppressing its signals.
These therapies have transformed the lives of many of our patients — including international visitors who had tried multiple conventional treatments without success.
What Is Neural Therapy?
Neural Therapy is a medical treatment that uses precisely targeted injections of local anesthetic — typically procaine — to regulate the autonomic nervous system and restore normal neurological signaling in areas of dysfunction.
The foundational principle of neural therapy is that many chronic pain conditions, functional disorders, and systemic health problems originate from disturbances in the autonomic nervous system — often triggered by trauma, surgery, inflammation, infections, or emotional stress at specific sites called "interference fields."
By injecting a local anesthetic into these interference fields — which may be located in scars, ganglia, nerve plexuses, or specific anatomical structures — neural therapy interrupts abnormal neurological signaling and allows the nervous system to reset and restore normal function.
Neural therapy can address conditions including:
- Chronic musculoskeletal pain — neck, back, shoulder, hip, and joint pain
- Post-surgical pain and scar-related dysfunction
- Headaches and migraines
- Autonomic nervous system disorders
- Chronic regional pain syndromes
- Visceral pain and functional organ disorders
- Stress-related pain and tension patterns
What Is Perineural Injection Therapy?
Perineural Injection Therapy (PIT) — also known as subcutaneous perineural injection therapy — is a minimally invasive treatment developed by Dr. John Lyftogt that targets neurogenic inflammation in superficial sensory nerves.
Many cases of chronic pain involve peripheral nerves that have become inflamed, sensitized, and dysfunctional — a condition called neurogenic inflammation. These sensitized nerves fire persistently, maintaining a state of chronic pain even when the original injury or cause has resolved.
Perineural injections deliver a low-concentration dextrose solution subcutaneously along the course of affected nerves. This solution reduces nerve inflammation, restores healthy nerve membrane function, and interrupts the cycle of neurogenic pain — often producing rapid and sustained pain relief.
Perineural injection therapy is particularly effective for:
- Peripheral neuropathy and nerve entrapment
- Chronic joint pain — knees, hips, shoulders, elbows, ankles
- Musculoskeletal pain from repetitive strain or overuse
- Sports injuries and ligament pain
- Headaches and occipital neuralgia
- Post-surgical pain and sensory nerve dysfunction
- Herniated disc-related nerve pain
- Plantar fasciitis and foot pain
How Neural and Perineural Therapy Work Together
At Rejuvilife, Dr. Alan Inman frequently combines neural therapy and perineural injection therapy in a single integrated protocol, addressing pain at both the autonomic nervous system level and the peripheral sensory nerve level simultaneously.
This combined approach produces synergistic results — deeper nervous system regulation through neural therapy, combined with targeted peripheral nerve repair through perineural injections — making it particularly effective for complex or treatment-resistant chronic pain conditions.
What to Expect During Treatment at Rejuvilife
Before your session
Dr. Alan Inman conducts a thorough evaluation of your pain history, functional limitations, previous treatments, and imaging studies if available. He identifies the specific neural interference fields and peripheral nerve pathways involved in your condition.
During your session
Injections are administered with very fine needles to specific anatomical targets. Most patients describe the procedure as minimally uncomfortable — significantly less painful than conventional cortisone or steroid injections. Sessions typically last between 30 and 60 minutes depending on the areas being treated.
After your session
Many patients experience notable pain relief within hours to days of their first session. Dr. Inman's protocol is designed to produce progressive and cumulative improvement over a series of treatments.
How Many Sessions Are Needed?
The number of sessions depends on the chronicity and complexity of your condition:
- Acute or recent injuries: 3 to 5 sessions may produce significant relief
- Chronic pain conditions: 6 to 10 sessions for meaningful and lasting improvement
- Complex or long-standing conditions: individualized protocols determined by Dr. Inman following initial evaluation
Sessions are typically scheduled once or twice per week during the initial treatment phase.
Real Patient Results at Rejuvilife
Neural and perineural therapy have produced some of the most dramatic patient outcomes at Rejuvilife. Our patient reviews describe results that many had stopped believing were possible after years of conventional treatment:
Patients with herniated discs and years of chronic back pain walking without pain or braces after a single session. Athletes eliminating stubborn joint and muscle pain that had resisted months of physical therapy. Post-surgical patients finding relief from pain that had persisted long after their recovery period.
These results reflect the power of addressing pain at its neurological source — rather than masking it with medications or managing it indefinitely.
Neural & Perineural Therapy for International Patients
Neural and perineural injection therapy are ideal treatments for international patients visiting Rejuvilife in Costa Rica. A meaningful treatment course of 5 to 10 sessions can be completed within one to two weeks, making it well-suited for patients traveling from the United States, Canada, or Europe.
Many international patients combine neural and perineural therapy with other treatments at Rejuvilife — such as NESA Microcurrents, Hyperbaric Oxygen Therapy, and IV nutrient support — for a comprehensive pain relief and recovery protocol during their stay.
We offer remote consultations before your arrival so Dr. Inman can review your history, imaging, and previous treatments in advance — ensuring your protocol is ready from day one of your visit.
Is Neural or Perineural Therapy Right for You?
These therapies may be appropriate if you are experiencing:
- Chronic neck, back, shoulder, hip, or joint pain
- Nerve pain, neuropathy, or nerve entrapment
- Post-surgical pain or scar-related dysfunction
- Sports injuries or repetitive strain conditions
- Headaches or migraines with a musculoskeletal component
- Pain that has not responded adequately to conventional treatments
- Desire to reduce or eliminate dependence on pain medications
A medical consultation with Dr. Alan Inman is required to evaluate your condition and determine whether neural or perineural therapy is appropriate for you.
