Trigeminal Neuralgia as the Only Neurological Manifestation of COVID-19: A Rare Case.

Trigeminal neuralgia is a neuropathic disease characterized by severe pain that reduces the patient's quality of life. This case report presents a Coronavirus Disease 2019 (COVID-19) positive case whose only neurological symptom is trigeminal neuralgia. A 59-year-old male patient with complaints of weakness, joint pain, cough, and respiratory failure was diagnosed with COVID-19. The patient was started on COVID-19 treatment and quarantined. Severe pain occurred on the right side of the patient's face on the third day of the onset of COVID-19-related complaints. There was severe pain in the distribution region of the maxillary and mandibular nerves, occurring 10-20 times a day and lasting 1-2 minutes. The patient was diagnosed with trigeminal neuralgia, and carbamazepine was started. Within three days, a significant decrease was observed in the complaint of pain. It should be kept in mind that SARS-CoV-2 may cause trigeminal neuralgia by activating the trigeminal nerve. [ABSTRACT FROM AUTHOR]
