Edition 14 – Is the Trigeminocervical Complex (Really) Related to Shoulder and Arm Symptoms?

“Okay, it’s been valuable to discuss the limitations of anaesthetic blocks in diagnosing headache; I gather you have issues with other diagnostic criteria (Edition 13 – The Role of Anaesthetic Blocks in Headache) for Cervicogenic Headache (CGH),” continues Watson’s colleague.   “Yes, particularly strictly unilateral pain without side-shift, and whilst this can be a manifestation of

Edition 13 – The Role of Anaesthetic Blocks in Headache

Watson’s colleague is keen to continue discussing the diagnostic criteria for cervicogenic headache (CGH), especially given Watson’s intense reply to his earlier query… “I understand you are generally ambivalent about the International Classification of Headache Disorders-3 (ICHD-3) diagnostic criteria for cervicogenic headache?”. The Irony of the CGH Diagnosis “Yes, but it is not only the

Edition 11 – Reproduction and Resolution of Headache – Significant?

The Background Whilst aware of the neuroscientist’s eagerness to his query of the neurophysiological effect of reproduction and resolution (R&R) on nociceptive blink reflex (R2), see Edition 10 – Revisiting the Role of Conditioned Pain Modulation During Reproduction and Resolution of Head Pain, Watson feels it essential to provide some background.  “Well, before we discuss

Edition 10 – Revisiting the Role of Conditioned Pain Modulation During Reproduction and Resolution of Head Pain

The neuroscientist, keen to follow up on the notion of reproduction and resolution (R&R) of head pain activating conditioned pain modulation (CPM), comments, “Well the prevailing perspective is that sensitisation of the Trigemino Cervical Complex (TCC) results from dysfunctional CPM.” “Yes, but the research is equivocal,” counters Watson’s colleague. Nociceptive Blink Reflex Watson then recalls
