Can a severe blow to the back of your head cause your entire body to feel like it's on fire it never leaves even things you eat cause you to burn severely in your entire body

My body feels like it is on fire it has been this way for years from a blow to the back of the head I was told by a neurologist I take lorazepam Klonopin if I don't take enough anything I eat causes me to burn severely even more than I already do
