Has anyone else had headaches that hit suddenly, intensely, and literally stop you in your tracks? It's the way it comes on that frightens me. It could happen in the middle of a sentence, walking down the street or watching TV. I've had them waken me out of a sleep. My eyes water, I hear a Buzzzz that blocks everything else out and I have no alternative but to just wait for it to disappear, hopefully but not usually, as quickly as it appeared. The pain is so intense it immobilizes me. Duration and frequency change. I am managed on one 325 mg aspirin/day for APS and 1 mg. Clonazapam 2x day to stop stuttering, severe right hand tremor, weak left side received via stroke (attributed to CNS vascuitis) about 10 yrs ago, and a trial of CQ10, 300 mg./day, in hopes of decreasing muscle/bone pain. Since the headaches were there before the trial of CQ10, I've ruled that enzyme out as a cause. It was witnessed by my MD as one happened during an appointment. Dhe did not think it a migraine as we timed it in her office and it lasted about six minutes. She offered to send me to a headache specialist, but I declined and now I wonder if that is the way to go or if its more money for no answers. I've just had so many doctors (most of which I have worked with) that have differing opinions that I've lost faith and trust in them. What say the APS population here? Does anyone else have headaches that manifest in a "wave" pattern and loud buzzing sound?
