Small Fiber Neuropathy
Don’t let small fiber neuropathy keep you from living comfortably or doing the things you love. At Compass Pain and Wellness, we combine advanced diagnostic medicine with regenerative therapies designed to treat the underlying nerve dysfunction—not just mask the symptoms.
Overview
What Is Small Fiber Neuropathy?
Small Fiber Neuropathy (SFN) is a condition that affects the small sensory nerve fibers responsible for transmitting pain, temperature, and autonomic signals throughout the body. Unlike large fiber neuropathies, which affect muscle strength and coordination, small fiber neuropathy primarily impacts the nerves responsible for sensation and internal body regulation.
These nerves play a critical role in the nervous system by helping the body detect temperature changes, pain, and regulate functions such as sweating, blood pressure, and heart rate. According to the Cleveland Clinic, damage to these small nerve fibers can lead to burning pain, abnormal sensations, and autonomic dysfunction that can significantly affect quality of life.

Expert Analysis
Understanding Small Fiber Neuropathy
Small fiber neuropathy typically begins with sensory disturbances in the feet and hands, though symptoms may eventually spread to other areas of the body. Many patients describe sensations such as burning, tingling, stabbing pain, electric-shock feelings, or extreme sensitivity to touch. Because these small nerve fibers also influence autonomic functions, some individuals may experience symptoms like abnormal sweating, dizziness, or gastrointestinal irregularities.
If left untreated, the condition may progressively worsen as nerve irritation and inflammation continue. Over time, the nervous system can become increasingly sensitized, meaning that normal stimuli may trigger exaggerated pain responses. Research from the National Institute of Neurological Disorders and Stroke indicates that small fiber neuropathy is often associated with metabolic disorders, autoimmune conditions, or chronic inflammation affecting peripheral nerves.

Triggers
Small fiber neuropathy can be triggered by a variety of underlying conditions that damage or irritate peripheral nerves. One of the most common causes is metabolic dysfunction such as diabetes or prediabetes, which can impair nerve health through prolonged elevated blood sugar levels and inflammation.
Other potential triggers include autoimmune disorders, infections, vitamin deficiencies, toxin exposure, genetic predisposition, and chronic inflammatory conditions. In some cases, the exact cause remains unclear and is referred to as idiopathic small fiber neuropathy. Factors such as chronic stress, poor circulation, and systemic inflammation may worsen symptoms by further irritating already sensitive nerve fibers.

Differential Diagnosis
Because the symptoms of small fiber neuropathy can resemble many other neurological or musculoskeletal conditions, careful evaluation is essential for an accurate diagnosis. Conditions that may produce similar symptoms include peripheral neuropathy involving large nerve fibers, nerve compression syndromes, radiculopathy from spinal disc problems, fibromyalgia, complex regional pain syndrome (CRPS), and autoimmune neurological disorders.
At Compass Pain and Wellness, our physicians specialize in identifying the root causes of complex nerve-related pain. Using advanced diagnostic tools—including nerve conduction velocity testing, imaging such as MRI, detailed neurological examinations, blood testing, and structure-specific diagnostic ultrasound—we evaluate the nervous system thoroughly. Accurate diagnosis is the foundation of effective treatment; you cannot develop the right treatment plan until you clearly understand what condition is present.
Solutions
At Compass Pain and Wellness, our treatment philosophy focuses on supporting nerve healing, reducing inflammation, and restoring proper neurological signaling. Because small fiber neuropathy often involves nerve irritation and inflammatory damage, our therapies are designed to promote nerve repair and improve nervous system function.
Our multidisciplinary team creates personalized treatment plans that combine regenerative medicine with targeted therapies that support neurological recovery and pain relief.
Treatment options may include:
Epidural steroid injections
Spinal cord stimulation for severe or treatment-resistant neuropathic pain
Advanced Neuromodulation: Spinal Cord Stimulation
For patients with severe neuropathic pain that does not respond to conservative treatments, spinal cord stimulation (SCS) can be a highly effective option. These small implantable devices deliver gentle electrical signals to the spinal cord, modifying pain signals before they reach the brain and significantly reducing neuropathic pain.
Spinal cord stimulation begins with a temporary trial period, allowing patients to experience relief before a permanent device is placed. At Compass Pain and Wellness, our physicians perform these procedures using advanced imaging guidance to ensure precise placement and optimal outcomes for patients suffering from chronic nerve pain.

What Makes Compass Different
At Compass Pain and Wellness, we believe that successful treatment begins with exceptional diagnostic medicine. Our board-certified physicians have more than 20 years of experience diagnosing and treating complex chronic pain conditions. Using advanced technologies—including flexion-extension X-rays, diagnostic ultrasound, MRI imaging, nerve conduction testing, and comprehensive laboratory evaluation—we identify the exact cause of nerve dysfunction rather than relying on symptom-based assumptions.
Once the root cause is identified, we provide the world’s most advanced regenerative medicine therapies, including platelet-rich plasma and cellular therapy, administered with precise ultrasound and fluoroscopic guidance to ensure accurate placement. In addition, our integrated care model provides patients with access to a full team of specialists—including physical therapists, acupuncturists, chiropractors, and massage therapists—along with advanced technologies such as photobiomodulation, PEMF, and shockwave therapy. This collaborative approach allows us to support healing at every level of the nervous system.
Ready to Transform?
Outlook
Living with small fiber neuropathy can be frustrating and painful, but effective treatment begins with identifying the root cause of nerve irritation and supporting the body’s natural healing processes. With the right combination of advanced diagnostics, regenerative therapies, and multidisciplinary care, many patients experience meaningful improvements in both pain and nerve function.
At Compass Pain and Wellness, we are committed to helping patients regain control over their health and quality of life. You don’t have to continue living with chronic nerve pain. Schedule a consultation today to learn how our comprehensive approach can help restore nerve function and get you back to the activities you love.
