Hello. I recently receive a head and back injuries that I had checked out last week. The CT scan on head, neck, and spine came back clear. I've just been dealing with pain in those areas and in and off nausea, some dizziness. Earlier today I had a dull to moderately painful headache that seems to have gone away but now I feel like I could faint, especially when I'm standing. Should I see a doctor or is this more of what I should expect for this type of injury?
