I had an increase of intracranial pressure caused by the auto accident/concussion and it made me have weird tinnitus and high blood pressure and other symptoms like severe headaches. They administered a spinal tap and it completely went away, no problem. If that's what you have, they'll figure it out and give you the right treatment. If you don't have headaches, or other debilitating symptoms, I wouldn't worry about it too much. Oh, it took them 6 months to figure out that's what I had before it was treated.... Crazy, right?
