I had it before at my bad times- and occasionally still if I get tight or mini spams in the neck area.
I found a few things that might explain it -
[As the head and neck are brought forward, the patient is forced to extend the occiput to keep the eyes horizontal, resulting in overactivity of the suboccipital muscles. With the head in a forward position, a passive tensile force is created in the hyoid muscles resulting in hyoid muscle tension, causing the mandible to be depressed and translated posteriorly. The patient is therefore forced to contract the temporalis and masseter muscles to keep the mouth closed.
This abnormal mandibular positioning can cause myofascial stress to the masseter and temporalis and temporomandibular problems. Porterfield and DeRosa1 state that symptoms such as excessive dry mouth due to mouth breathing, dysphagia, suboccipital headaches, teeth clenching, pain in the head and face over the temporalis area, and tightness over the throat region may occur.]

and [The pain referral pattern of the SCM includes pain over the cheekbone, in the forehead, on top of the head, in and behind the ear, over the chin, over the SC joint, over the forehead, and deep in the throat.3 The throat referral is a commonly overlooked cause of sore throat, often mistaken for pharyngitis. The patient will often feel a fullness in the throat, especially upon swallowing, which feels like a partial obstruction. The forehead referral pattern is one of the very few instances, if not the only instance, where referred pain can cross the midline, as the pain is frequently felt in the contralateral forehead area in a patient suffering from a TP in the clavicular division of the SCM.]
