Scalp Pain Causes and Diagnosis

Infectious Causes

Tinea capitis, a fungal infection, can present with painful inflammatory variants such as kerion, characterized by a painful, boggy, inflammatory mass with associated hair loss, pustules, and regional lymphadenopathy, as reported by the British Journal of Dermatology 1, 2
Favus, a chronic inflammatory tinea capitis, can present with yellow crusted cup-shaped lesions around follicular openings and may cause discomfort, according to the British Journal of Dermatology 1, 2

Psoriasis of the scalp can cause pain, particularly during treatment with certain modalities, as noted by the British Journal of Dermatology 4
Temporomandibular disorders (TMD) can refer pain to the scalp area, affecting 5-12% of the population with a peak age of 20-40 years, as reported by the British Journal of Anaesthesia 6

Giant cell arteritis should be suspected in elderly patients presenting with scalp tenderness, jaw claudication, and pain, requiring immediate evaluation, as recommended by the American Academy of Ophthalmology 7, 8, 9
Maxillary sinusitis can refer pain to the scalp region, particularly when associated with dental infections or procedures, as noted by the British Journal of Anaesthesia 6

Spontaneous intracranial hypotension can present with orthostatic headache that may involve the scalp, worsening within 2 hours of becoming upright and improving after lying flat, as reported by the Journal of Neurology, Neurosurgery and Psychiatry 10
Salivary gland disorders, particularly stones in the submandibular gland, can cause referred pain to the scalp area, as noted by the British Journal of Anaesthesia 6

For suspected infectious causes, appropriate samples should be collected for microscopy and culture, as recommended by the British Journal of Dermatology 1, 2
For suspected giant cell arteritis, immediate blood tests and consideration of temporal artery biopsy are essential, as recommended by the American Academy of Ophthalmology 7, 8, 9

Treatment should be directed at the underlying cause, such as antifungals for tinea capitis or steroids for inflammatory conditions, as recommended by the British Journal of Dermatology 1, 2
For giant cell arteritis, immediate consultation with a neuro-ophthalmologist and initiation of treatment is crucial, as recommended by the American Academy of Ophthalmology 7, 8, 9
For TMD-related scalp pain, approaches may include education, intraoral appliances, cognitive behavior therapy, and physiotherapy, as noted by the British Journal of Anaesthesia 6
