Neuropathy Condition
Small Fiber Neuropathy
The neuropathy a standard EMG can miss.
Small fiber neuropathy is damage to the smallest nerve fibers — the ones that carry pain and temperature signals and help run automatic functions. It causes burning, stabbing, and hypersensitivity, often with completely normal EMG results. Your symptoms are real, and they have an explanation.

Understanding Small Fiber Neuropathy
What It Is & Why It Happens
Your peripheral nerves come in sizes. Large fibers carry strength, vibration, and position sense; small fibers carry pain and temperature and help regulate automatic functions like sweating. Small fiber neuropathy means the small fibers are damaged while the large ones may still be working — which is why you can have burning feet at night and still pass a strength test with flying colors.
This is also why so many small fiber patients feel dismissed. Standard EMG and nerve-conduction studies primarily measure the large, fast fibers — they can come back completely normal while the small fibers are genuinely struggling. If you've been told 'your tests are fine' while your feet burn, itch, or stab, small fiber involvement is one of the most common explanations. The symptoms were never in your head; they were in fibers the test wasn't designed to see.
There is genuinely hopeful news here: small fibers have meaningful regenerative capacity when the environment around them improves. Because small fibers depend heavily on healthy microcirculation, our program focuses on measuring and supporting exactly that — circulation, inflammatory load, and sensory function — with objective testing at the start and progress re-exams along the way. An honest assessment of how much fiber function remains always comes first.
Common Symptoms
Signs You May Be Dealing With Small Fiber Neuropathy
- Burning pain, usually starting in the feet — often worst at night
- Sharp, stabbing, or electric-shock sensations
- Pins and needles or prickling that comes in waves
- Hypersensitivity — bedsheets or light touch feel painful
- Trouble telling hot from cold accurately
- Itching, crawling, or 'bugs on the skin' sensations with nothing visible
- Changes in sweating, or feet that look red or feel hot

How We Help
Our Treatment Approach
Dr. Logan Swaim, MS, DC has spent years specializing in peripheral neuropathy. Every program begins with a comprehensive nerve function assessment before any treatment is recommended.
- Comprehensive baseline testing: 16-point sensory exam, circulation assessment, and balance testing — the functional measures small fiber problems actually show up on
- Careful history to identify likely drivers (blood-sugar trends, autoimmune factors, nutritional gaps) and coordinate any needed medical workup
- Red light therapy (photobiomodulation) to support the microcirculation small fibers depend on
- Chiropractic neurological care to support the structural environment of the nervous system
- Nutritional guidance where deficiencies commonly accelerate small fiber damage (B vitamins, alpha-lipoic acid, magnesium)
- Objective progress re-exams so improvement in sensation and circulation is measured, not guessed
