Blindindicator,
I will make this short. My daughter had a concussion 4.5 yrs ago. All the doctors thought that her symptoms were PCS but we have come to find out through extensive vestibular testing that it is actually migraine related. (A migraine gene was triggered throughout the head injury was how it was explained to us.) The head doctor for the vestibular clinic said that what we thought was PCS was actually a type of migraine. When we thought she was having a relapse, she was actually triggering the headache. We are now working with a doctor at UCSF med. to help find a medication that would prevent the migraine from occurring. (Light sensitivity was really bad for her)

She also benefitted from prism glasses.

Acupuncture has helped stop her migraines although the affects from acupuncture only lasts a few days. It is well worth the price to be headache free for a few days.

But the most beneficial help to date was doing the hyperbaric study in New Orleans with Dr Harch. The treatment was free but we had to pay for the lodging and travel. You can google him and call to see if the study is still going on.

There are many complications from a head injury...neck injuries. eye tracking, etc

Try not to lose hope.

My best,
