• ***La “cervicale”: è forse la diceria più frequente. E pensare che la Classificazione Internazionale delle Cefalee non solo non la prevede ma addirittura esclude che la “cervicale” sia causa di per sè di alcun tipo di cefalea! Piuttosto occorre sapere che l’emicrania può nascere dal collo o può estendersi al collo senza che questo voglia dire assolutamente nulla sullo stato delle articolazioni e dei muscoli cervicali. Spesso il dolore cervicale in corso di emicrania è solo un dolore “riferito”, nè più nè meno del dolore al braccio sinistro che può comparire nell’infarto miocardico****.
• La “sinusite”: altra favola dura a morire. Un po’ di chiarezza 1) la sinusite cronica non da mai cefalea; 2) la cefalea in corso di sinusite acuta deve essere associata a secrezione nasale muco-purulente, rinite, febbre e sintomi di infezione. Questo vuol dire che cefalee da patologie dei seni paranasali sono molto rare.

Cervical headaches
Pain from the cervical region (arising from periosteum, ligaments, nerve irritation, or reflex muscle spasm) is usually felt over the neck and occiput, but can be referred around the temples and even into the frontal region. In a person with a history of neck trauma or with symptoms or signs of cervical root or cord compression, cervical imaging with MR or a CT scan must be obtained to rule out a condition that might result in cord compression, such as fracture or dislocation. Cervical spine x-rays with lateral views in flexion and extension are useful to detect excessive mobility of the spine.

What is a Cervical Headache?

Cervical headaches or cervicogenic headaches are headaches caused by abnormalities in the cervical (neck and head) region, the cause is variable as described above. The mechanism of production of the headache is also variable. It can be referred from the upper cervical nerve roots, segments of the cervical spine which can irritate some of the sensory nerves. Headaches can be caused by trigger points in the neck muscles and head muscles.
