If your Physician is in a practice group that covers for each other, they would be the ones to at the least change your medication first - ask the office about that....explain you would like to deal with that first.

While with that physician - who will most likely want to see you, you can discuss Neurologists - and it would be best to have a referral to one with experience with Head Injuries (concussions, Brain Contusion patients).

If they are not aware of any, or you are able to self refer, re: your insurance - not knowing your locale - I would recommend checking with UT, Baylor Neuroscience Centers for recommendations, even Scott & White, even those Neuro-Sensory Centers of Baylor or in Austin I had noted? - They have Neurologists, Neuro-ENT specialists also.

(Note/disclaimer: I used to work contract work in Texas in Houston, Mexia, and Commerce, so do recall some of the referral areas, or at least names of them for reference only - I used to refer to Baylor and UT quite often; just now can't recall if those are the same; Scott & White was growing so large, I don't know if its outgrown its helpfulness to its patients or not, and just become a big business now)

But, more on point, you need a Neurologist with experience in Head Injury (particularly with Concussions and Brain Contusions).

Good Luck, Best Wishes.
