Tingling Sensation Over the Head

Causes

1. Neurological Causes

• Cervical spine disease - Degenerative disk disease of the cervical spine is one of the most frequent underlying causes. Chronic tension on the occipitofrontalis muscle and scalp aponeurosis is the proposed mechanism. (Andrews' Diseases of the Skin, p.76)
• Occipital neuralgia - Irritation or entrapment of the greater or lesser occipital nerves causes tingling/shooting pain radiating from the back of the head upward; often mistaken for a headache
• Trigeminal nerve involvement - The trigeminal nerve branches supply the forehead and scalp; irritation causes paroxysmal or persistent tingling in its distribution
• Multiple sclerosis (MS) - Demyelinating lesions can produce paresthesias anywhere including the scalp and head
• Stroke or TIA - Vascular events affecting sensory cortex can cause sudden-onset head or face tingling; this is a red-flag symptom
• Small-fiber neuropathy - Caused by diabetes, vitamin deficiencies (B12, B1), or other metabolic disorders

2. Dermatological Causes

• Scalp dysesthesia (burning scalp syndrome) - Presents with diffuse burning, pain, numbness, or tingling of the scalp without objective findings. Secondary causes like seborrheic dermatitis, folliculitis, lichen planopilaris, and contact dermatitis must first be excluded. Often associated with depression and anxiety. (Dermatology 2-Volume Set 5e)
• Head lice (Pediculosis capitis) - One of the earliest signs is a tingling/crawling sensation on the scalp
• Ringworm (Tinea capitis) - Fungal infection causing scalp tingling and sometimes hair loss
• Contact dermatitis - Allergic or irritant reaction to hair products, dyes, or shampoos
• Seborrheic dermatitis - Can be accompanied by scalp dysesthesia

3. Psychiatric / Psychogenic Causes

• Anxiety and stress - Hyperventilation and the autonomic stress response can trigger tingling sensations. A psychiatric overlay is frequently associated with scalp dysesthesia.
• Depression - Scalp dysesthesia is closely linked to depressive disorders
• Somatoform disorders

4. Vascular / Migraine-Related

• Migraine with aura - Tingling in the scalp/face can be part of the migrainous aura
• Giant cell arteritis (temporal arteritis) - Important in elderly patients; causes scalp tenderness and tingling along the temporal arteries, with risk of blindness if untreated

5. Metabolic / Nutritional

• Vitamin B12 deficiency - Causes peripheral and central neuropathy with paresthesias
• Diabetes mellitus - Peripheral neuropathy can extend to the scalp
• Hypothyroidism - Can cause diffuse tingling

6. Medications / Iatrogenic

• Prior brow lift or facelift surgery - Surgical trauma to facial/scalp nerves is a recognized cause of scalp dysesthesia
• Certain medications (e.g., BRAF inhibitors like sorafenib) - Facial and scalp dysesthesia occurs in ~60% of sorafenib-treated patients

7. Infections

• Herpes zoster (shingles) - Reactivation of varicella-zoster virus along a cranial nerve (often V1/ophthalmic division or the occipital nerves) causes burning, tingling, and eventually vesicles
• Post-COVID-19 syndrome - Scalp dysesthesias have been reported as a post-infectious phenomenon after COVID-19

Red Flag Symptoms - Seek Immediate Care

Diagnosis

1. Take a detailed history (onset, duration, triggers, associated symptoms, medications, prior surgeries)
2. Perform physical and neurological examination
3. Consider:
   • Skin biopsy if a dermatological cause is suspected
   • MRI of the brain/cervical spine for neurological causes
   • Nerve conduction studies for peripheral neuropathy
   • Blood tests: B12, glucose, TSH, inflammatory markers (ESR, CRP for giant cell arteritis)
