I am a 29 year old that has anxiety. Over the last couple months I have had several episodes where I get a sharp shooting pain in the side of my head that lasts for less than 30 seconds. It feels like I am going to fall down, I get sweaty and start stressing about this and it goes on for hours although the headache was only for a moment. Could someone please explain what is going on or what this is. Also could it be linked to the anxiety.
