What Causes Burning Feet in Neuropathy Patients?
Understanding the medical causes behind burning feet in neuropathy patients and evidence-based treatment approaches from Idaho Falls specialists.
Burning feet is one of the most distressing symptoms experienced by neuropathy patients. This uncomfortable sensation, often described as walking on hot coals or electric shocks shooting through the feet, affects millions of Americans and is particularly common among diabetics.
As specialists in neuropathy treatment at Eagle Rock Neuropathy and Pain Center in Idaho Falls, we see patients daily who struggle with burning feet. Understanding the underlying mechanisms and available treatments is crucial for finding effective relief.

Understanding the Burning Sensation
What Happens in Your Nerves
The burning sensation in neuropathy occurs when peripheral nerves become damaged and begin sending incorrect signals to the brain. These damaged nerves, particularly small unmyelinated C-fibers responsible for pain and temperature sensation, fire spontaneously or become hyperexcitable.
🔑 Key Takeaways: Nerve Damage Mechanism
- • Small Fiber Damage: C-fibers and A-delta fibers become hyperactive
- • Spontaneous Firing: Damaged nerves send pain signals without stimulus
- • Neuroinflammation: Immune system activation worsens nerve sensitivity
- • Central Sensitization: Brain amplifies pain signals over time
Primary Causes of Burning Feet
1. Diabetic Neuropathy
The leading cause of burning feet, affecting 60-70% of diabetics. High blood glucose levels damage nerve fibers through multiple mechanisms:
- • Advanced glycation end products (AGEs)
- • Oxidative stress and inflammation
- • Reduced nerve blood flow (ischemia)
- • Metabolic disruption of nerve function
2. Peripheral Artery Disease
Poor circulation reduces oxygen delivery to nerves, causing burning and pain, especially during activity.
- • Reduced blood flow to nerve tissues
- • Ischemic nerve damage
- • Often coexists with diabetes
- • Symptoms worsen with walking
3. Vitamin Deficiencies
Nutritional deficiencies, particularly B vitamins, can cause burning neuropathy symptoms.
- • B12 deficiency (most common)
- • Thiamine (B1) deficiency
- • Folate deficiency
- • Often reversible with supplementation
4. Medications & Toxins
Certain medications and toxic exposures can cause burning neuropathy as a side effect.
- • Chemotherapy drugs
- • Some antibiotics
- • Heavy metal exposure
- • Alcohol-related neuropathy

Frequently Asked Questions
Why do my feet burn more at night?
Burning feet often worsen at night due to several factors: reduced distractions allow you to focus on the pain, lying down can reduce blood flow to feet, and temperature changes in bed can trigger nerve hypersensitivity. This pattern is classic for small fiber neuropathy.
Can burning neuropathy be reversed?
While nerve damage is often permanent, the burning pain can be effectively managed and sometimes reduced with proper treatment. Early intervention with treatments like PNS can prevent progression and provide significant relief. Some causes, like vitamin deficiencies, are reversible if caught early.
How long does burning neuropathy last?
Without treatment, burning neuropathy tends to be chronic and may worsen over time. However, with appropriate medical management, including treatments like PNS therapy, many patients experience significant long-term relief. Our clinic has helped patients maintain pain relief for years with proper treatment protocols.
