The sensitivities to burning pain and capsaicin of Japanese adult subjects were compared with their TRPV1 genome sequence, and we detected 6 single-nucleotide polymorphisms and 11 single-nucleotide polymorphisms related to burning pain and capsaicin sensitivity, respectively.
When expressed by sensory neurons, activation of TRPV1 channels by heat (>40 °C), capsaicin (sub-micromolar), or acid environment (pH < 6), causes depolarization leading to burning pain sensation in mammals.
Capsaicin is an ingredient in spicy peppers that produces burning pain by activating transient receptor potential vanilloid 1 (TRPV1), a Ca<sup>2+</sup>-permeable ion channel in nociceptors.
Fabry disease (FD) is an X-linked lysosomal storage disorder that leads to cellular globotriaosylceramide (Gb3) accumulation due to mutations in the gene encoding α-galactosidase A. Trigger-induced acral burning pain is an early FD symptom of unknown pathophysiology.
Because Fabry disease and primary erythromelalgia share similar symptoms, it is a good strategy for clinical physicians to perform genetic mutation screenings on both SCN9A and GLA genes in those patients with limb burning pain but without a clear inheritant pattern.
Clinically, ADC gel does not have any side effects and discomfort such as pain, burning, tingling sensation or numbness and produces no adverse reactions in time.

Erythromelalgia due to heterozygous gain-of-function SCN9A mutations usually presents as a pure sensory-autonomic disorder characterized by recurrent episodes of burning pain and redness of the extremities.
Our clinical and skin biopsy study showed that ongoing burning pain was strongly associated with regenerating sprouts, as assessed with GAP43 immunostaining.
Involvement of brain-derived neurotrophic factor (BDNF) in chronic intermittent stress-induced enhanced mechanical allodynia in a rat model of burn pain.
