In the early hours of the morning, around 2am, I wake from sleep with a hot pulsing feeling in my head. I can t move, and just lie there feeling like crap. After a few minutes I pluck up the courage to move and grab water. It takes about 15 mins to go away. I wake again in the morning with a sore neck.
If that pulsating headache disturbs your sleep in night, it is a matter of concern. You must get it investigated to rule out any intracranial lesion. Also, there is strong possibility of "cluster headache", which is a clinical diagnosis, for which you must consult a neurologist.
