What Is Perineural Injection Therapy?

Perineural Injection Therapy (PIT) is a safe and effective technique for managing pain across various conditions. Developed by Dr. John Lyftogt, it involves targeted 5% glucose injections along the course of subcutaneous nerves. The treatment aims to restore movement and reduce pain in the area treated, by reducing neurogenic inflammation generated by irritated nerves.

PIT is effective in treating many painful musculoskeletal conditions, including, but not limited to:

  • Shoulder impingement
  • Frozen shoulder
  • Hip and knee pain
  • Tennis elbow
  • Neck-related headaches
  • Chronic neck and back pain
  • Recent soft tissue injuries
  • Achilles tendinopathy

How does it work?

Glucose is an essential energy source for all cells, including nerve cells. The nerve supply and blood supply to a nerve become compromised if it is injured, compressed, or stretched anywhere along its path. Because of this, fewer nutrients, like glucose, reach the nerve, which causes the nerve to become stressed at that location.

A damaged nerve begins to swell, become irritable, hypersensitive, and fire more rapidly, resulting in pain. In an effort to heal itself, the nerve also produces inflammation. If the swelling and compression persist, these inflammatory substances further irritate the nerve.  The fuel required to reduce swelling and abnormal firing, as well as to restore normal nerve function and healing, is provided by injecting 5% glucose around these sensitized and irritable nerves.  As a result, pain is immediately reduced, and range of motion and function is enhanced.

What does the treatment involve?

Following an initial discussion and examination to determine if the treatment is suitable for you, tender points in the field of the irritated nerve are identified. PIT injections are administered with very small and short needles just beneath the surface of the skin. Multiple injections are performed along the course of subcutaneous nerves. You may experience mild discomfort, generally, this will subside within a few minutes. 

Treatments are repeated every 1-2 weeks until all the pain has resolved. Typically, patients require between 4-8 treatments in total. This can differ depending on how long the injury has been present as well as the degree of the damage. When pain returns, it is usually substantially less severe. 

The technique aims to improve movement and reduce pain in the area treated at the time of treatment. This analgesic, pain-relieving effect can last from a few hours to a few days. When pain returns, it is usually substantially less severe. On average, patients notice a 15-20% improvement after each treatment.
