2. Neuralgia (Greek neuron, "nerve" + algos,
"pain") is pain in the distribution of one or
more nerves,
• Neuropathic pain is pain caused by damage or
disease affecting the somato sensory system.
• Neuropathic pain may result from disorders of
the peripheral nervous system or the central
nervous system (brain and spinal cord).
4. Glossopharyngeal Neuralgia
• Pain in tonsillar fossa
• Back of the throat, larynx and radiating
towards ear
• Pain while Swallowing
• Not very common
5. Postherpetic neuralgia
• Occurs as a complication of Shingles a viral infection,
characterized by painful rash, blisters
• May be anywhere on the body
• Neuralgia can occur wherever the outbreak of shingles
• Pain can be mild/ persistent/ intermittent
• Some cases pain may occur before the rash
• Occurs along with the path of nerve so its usually isolated to
one side of the body
6. Occipital Neuralgia
• It is a condition in which the occipital nerves, the nerves
that run through the scalp, are injured or inflamed.
• Headache that feel like severe piercing, throbbing
• shock-like pain in the upper neck, back of the head or
behind the ears.
• generally starts at the base of the head and goes to the
scalp on one or both sides of the head.
7. Trigeminal neuralgia
• Trigeminal neuralgia (TN or TGN), also called Fothergill
disease, tic douloureux, or trifacial neuralgia is a long-
term pain disorder that affects the trigeminal nerve
• It is a neuropathic pain in the distribution of the one ore
more divisions of the Trigeminal neuron.
• TN Syndrome: Sudden, severe, paroxysmal of neuropathic
pain
8. • Unknown
• Infections
• Vascular compression on nerve root
• Exposure to cold, blow, chewing, eating, hot and
cold drinks
• Diabetes
• Less common causes - Chemical irritation
Trauma
Chroni kidney disease
9. Symptoms
• S – Site of the pain
• O – Onset
• C – Character
• R – Radiation
• A – associate with
• T – Time (duration)
• E – Exacerbating and
relieving
• S – Severity of pain

• SITE – Unilateral facial pain common in
mandibular, maxillary and ophthalmic region
• ONSET – sudden, paraxismal pain
• CHARACTER –cutting, stabbing, electrical shock
like
• RADIATION – angle of the mouth to ear, eye,
nostril
• ASSOCIATED WITH – spasticity, winces, flushing of
face, lacrimation
• TIME - 1 to 2 min duration only
• EXACERBATING AND RELIEVING FACTORS –
spontaneous, allodynia –
movement/smile/eating/chewing/swallowing,
soft touch- tactile allodynia
• SEVERITY – Very severe, cluster of attacks, jerks
11. Aetiology
Compression of blood vessels, esp.
superior cerebellar artery
Chronic irritation of Trigeminal
Nerve at the root
Increased firing of the sensory
fibres
TRIGEMINAL NEURALGIA
12. Types of trigeminal neuralgia
• CLINICAL TN: NO serious associated symptoms
NO sensory loss
NO interictal numbness
Blood vessel compressing to nerve
• SYMPTOMATIC TN : Sensory loss
Interictal facial numbness
Cranial nerve involvement
Myaline and Axon damage
