| Tumor
infiltration of a
peripheral nerve |
Constant burning pain with dysesthesia in an area of sensory loss. |
Peripheral nerves |
| Pain is radicular and often
unilateral. |
| Postradical neck
dissection |
Tight burning sensation in the area of sensory loss. |
Lower cranial nerves |
| Dysesthesias and shocklike pain may
be present. |
| Musculoskeletal pain may be caused by
a drooped-shoulder syndrome. |
Cervical plexus |
| Postmastectomy pain |
Tight, constricting, burning pain in
the posterior arm, axilla, and
anterior chest wall. |
Intercostobrachial |
| Pain exacerbated by arm movement,
possibly caused by musculoskeletal
dysfunction or edema. |
| Postthoracotomy pain |
Aching sensation in the distribution
of the incision with sensory loss
with or without autonomic changes. |
Intercostal |
| Often exquisite point tenderness at
the most medial and apical points of
the scar with a specific trigger
point in the muscle. |
| Postnephrectomy pain |
Numbness, fullness, or heaviness in
the flank, anterior abdomen, and
groin. |
Superficial cutaneous nerves |
| Dysesthesias are common. |
| Postamputation
pain |
Persistent, severe phantom limb pain in a minority of patients. |
Peripheral nerves and their central
projections
|
| Stump pain generally resolves with
wound healing, although pain associated
with scar sensitivity may emerge after
months or years. |
| Chemotherapy-induced
peripheral
neuropathy |
Painful paresthesias and dysesthesias. |
Peripheral nerves (e.g., polyneuropathy) |
| Hyporeflexia. |
| Less frequently: motor and sensory
loss; rarely: autonomic dysfunction. |
| Commonly associated with the vinca
alkaloids (e.g., vincristine, vinblastine), cisplatin, and paclitaxel. |
| Peripheral nerve
tumors
|
Radiation therapy may promote malignant fibrosarcoma. |
Peripheral nerves |
| Painful, enlarging mass in a
previously irradiated area. |
| Patients with neurofibromatosis more
susceptible. |
| Cranial
neuropathies |
Severe head pain with cranial nerve dysfunction. |
Cranial nerves V, VII, IX, X, XI, XII are most common. |
| Leptomeningeal disease. |
| Base of skull metastasis. |
| Acute and
postherpetic
neuralgia |
Painful paresthesia and dysesthesia. |
Thoracic and cranial nerve V are most common. |
| Constant burning and aching pain. |
| Shocklike paroxysmal pain. |
| Immunosuppression from disease or
treatment is a risk factor;
postherpetic neuropathy incidence
increases with age. |
