3 months after the return of symptoms (following a sprint) I am starting to feel better, but all the improvement has happened during the last 2 weeks.

Emotional problems delayed my recovery since I lacked sleep (my gf left me for another dude, how nice of her, 2 weeks after my concussion).

Question I saw a neuro 2 weeks ago and he recommended EEG for brain and "autonom test"... are these any useful in a case like mine? a casual read of the literature seems to suggest that months after injury these tests typically do not show much...

I am starting to feel better, and some days I am almost symptom free. My symptoms are mainly dizziness/light headedness and some low grade headache.

Thanks

Unless you are having seizure like symptoms, an EEG is likely just to rule out the obscure risks and to generate fees.

The autonomic nervous system test sounds extreme, too. He may be thinking it can help diagnose your dizziness.

Your symptoms do not sound like you need to push diagnostics. Hopefully, you will continue to improve as you already have.
