Trigeminal Neuralgia & Facial Lumps: What to Know

Trigeminal neuralgia (TN) causes sudden, severe, electric-shock facial pain along trigeminal nerve branches (V1 ophthalmic, V2 maxillary, V3 mandibular). Typically unilateral.

Classic TN Symptoms

• Paroxysmal, stabbing, shooting pain (seconds to minutes)
• Triggered by light touch, chewing, talking, cold wind
• Refractory period between attacks
• No sensory loss (classic TN)

Facial Lump ≠ Typical TN

A hard lump in front of the ear (preauricular area) suggests:

• Parotid gland tumor (pleomorphic adenoma, Warthin's, malignancy)
• Lymphadenopathy (infection, lymphoma, metastasis)
• Sebaceous cyst, lipoma
• TMJ disorder (bony prominence)
• Branchial cleft remnant

Action

• See ENT or neurologist promptly.
• Imaging (MRI/CT) for parotid/neck mass.
• Fine-needle aspiration if indicated.
• TN treatment (carbamazepine, oxcarbazepine, surgery) separate from lump evaluation.

TN doesn't cause lumps. Any new facial mass needs investigation.
