Are Lightheadedness And Sensitivity To Bright Light Normal After Landing On Tailbone?

Hi, may I answer your health queries right now ? Please type your query here...I fell hard on my tail bone a year or so ago. At that moment, I felt heat rise up from my tail bone to my head. Since then, I am lightheaded off and on, loud noises can make my balance off and so do bright lights. I have never felt normal since. I had a CT of my brain, and it was normal. I obviously have some nerve damage. I never went to a specialist for it. Also. when I sit on hard surfaces. it cam make me a little dizzy or light headed. Is this normal and how long will I luffer with this?
