Multiple concussions

Hi I just wanted some help on my situation. I played high school football in 2003-2004 and have no idea how many concussions I sustained. All I know is that it hurt to hit with my shoulders (shoulder tendonitis from swimming) so I hit with my head every time basically. Well, after practices some games I would just sit down dizzy and nauseas staring into space after hitting with my head so much. I finally had my season end in a game because on one of the hits I actually felt my brain vibrating inside my head and I fell on the ground and got blurry vision for 10 seconds. I felt completely out of it for 2 months after that hit.

I went on to try to play college football, stupidly. However, my head felt “soft” and would hurt very bad even after the most average of collisions. In the 2nd practice with helmets I fell down and threw up after contact with my helmet because I was so nauseas from the hitting.

Symptoms:
Now, I always feel a slight pressure in my head, and my head feels “soft” and I am 100x more likely to feel the pain of a hit to the head compared to what I used to be. My temples constantly ache and I rub on them all day to feel better. I also have a hard time just being in the moment. Its hard to explain, a beautiful scene in nature is hard for me to take in because I always feel a little “out of it”. I know I am not functioning at 100% anymore, probably more like 75%. I used to be a great writer and love to write papers eloquently, but after the concussions my writing was one of the worst things I did academically.

What I need help on is that I am afraid I may something such as hydrocephalus. What kind of a doctor should I make an appointment with to check this out? A neurologist? Also, check out traumatic brain encephalopathy. That is what I am a candidate for having. There has been studies in the national football league about players developing a tau protein build up in their brain after multiple concussions.

Where do I go from here? I have been looking into hyperbaric oxygen treatment. Money is not an issue, I don't think. I already started fish oil over 6 months ago to help out.
