Stimulation of the auricular branch of the vagus nerve supplying the ear may also elicit a cough. This ear-cough reflex is also known as Arnold's nerve reflex (ANR), linked to the auricular branch of vagus nerve. It is an example of vagal hypersensitivity.
This nerve may be involved by the glomus jugulare tumour. Laryngeal cancer can present with pain behind the ear and in the ear - this is a referred pain through the vagus nerve to the nerve of Arnold. In a small portion of individuals, the auricular nerve is the afferent limb of the Ear-Cough or Arnold Reflex. [3]
The hypersensitivity of vagal afferent nerves causes refractory or idiopathic cough. Arnold's nerve ear-cough reflex, though uncommon, is a manifestation of a vagal sensory neuropathy and this is the cause of a refractory chronic cough that can be treated with gabapentin. The cough is triggered by mechanical stimulation of the external auditory ...
The type of cough you have is a clue to what's causing it: A wet cough (the type that brings up phlegm or mucus) is often a sign of a lower respiratory infection.
The auricular branch of the vagus nerve was nicknamed "Arnold's nerve" after he described the reflex of coughing when the ear is stimulated. [2] Other eponyms that contain his name are "Arnold's ganglion" (otic ganglion) and "Arnold's canal" (a passage of the petrous portion of the temporal bone for the auricular branch of the vagus nerve.

(Migraine with aura is considered a separate condition and comes with an increased risk for stroke, the Mayo Clinic says.) During an aura, "there's a spontaneous firing of neurons in this visual ...
Norovirus cases are surging in the US, the CDC says. Here are the symptoms to look for, plus how long you're contagious for, per an infectious disease doctor.
Complications of reflex syncope include injury due to a fall. [1] Reflex syncope is divided into three types: vasovagal, situational, and carotid sinus. [2] Vasovagal syncope is typically triggered by seeing blood, pain, emotional stress, or prolonged standing. [11] Situational syncope is often triggered by urination, swallowing, or coughing. [2]
