How Can Post Concussive Syndrome Be Treated?

I need to speak to a neurologist. I have post concussive syndrome. I have a lot of symptoms. My PCP after a month decided to order an MRA/MRI. I got a call that it was set up for this Sunday. I couldn t understand the message so my fiancee listened. When calling them they only had the MRI set up. My insurance would not cover the MRA. My PCP was worried that I might have a slow brain bleed. I hit my head in the bottom base of my skull. I lose my speech, I am in space half of the time. I do have some lucid moments. It has been about six weeks. I did horrible on my neuro exam I guess. I thought I nailed it. I have not short term memory. I don t understand the t.v. Would an MRI show a brain bleed? I think Mike told me that was what the MRA was for. We cancelled the appointment for Sunday. This is my 4th or 5th concussion. Any information will help. I know PCS can take a long time to heal.
