I would go in and get a QEEG done from anyone how does neurofeedback. They all send their info to the same place, so it doesn't matter whether or not they use a computer or not (it actually is all analyzed on a computer anyway).

You should also consider doing some neurofeedback. It is very natural way to get your brain to heal. Also, eat lots of protein and take high doses of Vitamin B12 (there is not upper limit for B12, so don't worry about overdosing on it) and omega 3's. Make sure you are also getting your recommended daily dose of B6. And, cut back on the sugar and carbs.
You probably do have PCS, but with neurofeedback, you should be able to come out of it (no promises though).
