question: Hi, i have been getting brain misfiring which cause a short sharp and painful stabbing of pain which causes painful,soft areas beneath the skull. I have hollowed areas where they have happened. When they happen it is usually caused by stress (like a fright, multi tasking or getting overheated) . The areas that have been effected are left tender. i had one really big one behind the back of the ear and my jaw got locked, making it so tender that i couldn't chew for nearly a week.thanks Rosalyn
