I was in a severe car accident two years ago and ever since my neck cracks and when it does it causes severe pain. But if I don’t crack my neck i also have a build up of pressure on the base of my neck/skull that creates a headache if not realeaved by cracking my neck. Aside from pain when I crack my neck my ears ring really loudly and i get a dizzy spell. What can i do to help this issue? And what may be causing this issue. Thank you.
