Perinueral Injections for Tennis Elbow

Perineural Injection Therapy (PIT), also known as neurofascial prolotherapy, is a treatment aimed at relieving chronic pain by injecting a dextrose (sugar-water) solution near irritated or inflamed nerves. In the case of tennis elbow (lateral epicondylitis), which involves pain and inflammation where the forearm muscles attach to the outer elbow, PIT may offer several potential benefits:

What PIT Might Do for Tennis Elbow:
Reduce Nerve-Related Pain:
PIT targets the small sensory nerves in the superficial tissue. If pain from tennis elbow is partly due to chronic nerve irritation (as it often is), PIT may calm the nerves and reduce pain.

Interrupt Pain Signaling:
The dextrose solution may help “reset” overactive pain receptors in the nerve endings, especially in chronic cases where the pain persists after the initial injury heals.

Support Tissue Healing:
By reducing inflammation around the nerves and improving the local environment, PIT might support healing of the tendon and connective tissues indirectly.

Improve Range of Motion and Function:
With decreased pain, patients often find it easier to move the elbow, grip objects, and return to daily or athletic activities.

How It Compares to Other Treatments:
Unlike cortisone injections, which suppress inflammation but may weaken tendon tissue over time, PIT is generally considered non-destructive.

PIT is less invasive than surgery and may be considered if physical therapy, bracing, or standard prolotherapy haven’t worked.
