I've been have weird head sensations like little tingles in my head and sometimes I get waves that feel like they numb out my head or something. I really want to get a CT scan because I feel like I'm going to have a stroke or a blood clot or something really dangerous. I've been having panic attacks for like 2-3 months now. This all started like 9 months ago when I started having depersonalization which made me feel like if I was detached from my body somehow. Please help and reply. I've been freaking out for the past week I called 911 also.
