Etiologies of Intermittent Burning Triceps Sensation
Intermittent burning in the triceps region most often reflects either neuropathic pain from nerve irritation or musculoskeletal pain from myofascial or overuse mechanisms. (journals.physiology.org) The most common neuropathic pattern arises from a lesion affecting the cervical roots, brachial plexus, or peripheral nerve branches supplying the upper limb.

Neuropathic Etiologies From Nervous System Injury or Irritation
Neuropathic pain is commonly described as burning, shock-like, or shooting and may be continuous or intermittent. (pmc.ncbi.nlm.nih.gov)
Cervical radiculopathy
Pain from nerve root involvement in the neck can be experienced as burning quality in the arm. (pmc.ncbi.nlm.nih.gov)
Brachial plexopathy
Brachial plexus disorders can produce pain with a burning quality and sensory symptoms such as tingling. (pmc.ncbi.nlm.nih.gov)
Peripheral nerve entrapment
Entrapment syndromes in the upper limb can produce burning or other abnormal sensations in the distribution of the affected nerve. (pmc.ncbi.nlm.nih.gov) Ulnar nerve anatomy places it in proximity to triceps-region structures at the elbow, creating a mechanistic basis for symptoms that may be perceived near the posterior arm in some cases. (pmc.ncbi.nlm.nih.gov)
Peripheral neuropathy
Peripheral neuropathies can present with burning and other neuropathic descriptors as part of damaged small-fiber and peripheral nerve mechanisms. (pmc.ncbi.nlm.nih.gov)
Central neuropathic pain
Central neuropathic pain syndromes can produce intermittent neuropathic pain with burning descriptions. (tandfonline.com)
Myofascial and Musculoskeletal Etiologies
Myofascial pain syndrome is characterized by trigger points within taut muscle bands and can cause localized pain with referral patterns. (pmc.ncbi.nlm.nih.gov) Myofascial trigger point mechanisms include low-level contractions and direct trauma and are associated with characteristic referred pain patterns. (tandfonline.com) Unaccustomed eccentric loading and other muscle overload patterns are described as contributors to myofascial trigger points. (tandfonline.com)
Other Etiologies Described in Differential Diagnoses of Upper-Extremity Burning Pain
Upper-limb neuropathic descriptors also appear in broader differentials that include inflammatory, neoplastic, infectious, and compressive causes of nerve dysfunction. (pmc.ncbi.nlm.nih.gov)
Clinical Localization Clues That Support a Specific Etiology
A neuropathic mechanism is supported by burning quality with a neuroanatomic distribution and possible associated sensory symptoms. (pmc.ncbi.nlm.nih.gov) A myofascial mechanism is supported by pain related to identifiable trigger points and referred pain patterns. (pmc.ncbi.nlm.nih.gov)
Common Pitfalls to Avoid in Etiology Assignment
Burning pain should not be assumed to be purely muscular because neuropathic pain frequently presents with intermittent burning descriptors. (pmc.ncbi.nlm.nih.gov) A purely peripheral-muscle explanation should not be assumed when symptoms are consistent with nerve-root, plexus, or peripheral nerve involvement patterns. (pmc.ncbi.nlm.nih.gov)
Safety Considerations Prompting Urgent Evaluation
Nerve pain etiologies with systemic danger signals such as malignancy, infection, or other serious causes are included in brachial plexopathy differentials and warrant timely evaluation when suspected. (pmc.ncbi.nlm.nih.gov)
