I've had this symptom all the way through with ME, I wonder how many others get it and what is it exactly? I feel a strong abnormal pulse in the back of my neck and can feel it going up into my head. I'm fairly sure it's the blood vessel. But could it be an inflammation nerve pulse ? As I get very bad inflammation in my head, headaches which are of the expanding kind and there is also a feverish heat in the head as well, sinus inflammation also. Whenever I get the pulsing symptom I know it is a sign of a flare up and that my ME symptoms are going to intensify if I don't rest up. I take fish oils for inflammation and that does help but in winter I feel like I need more help. Does anyone else get that pulsing ? I take -D Ribose -fish oils -vit. b with magnesium powder -melatonin for sleep and that's all I take.
