It was months before I got to see a neurologist, and he didn't tell me anything useful. Apart from ruling out rare complications there's not really anything they can tell you that hasn't been said on this thread already, the most important of which in my experience is not to drink alcohol.

As you can see from the post above there are a lot of lifestyle changes which can give your brain a better chance to heal, so get on them straight away.

Apart from that just make sure the neurologist knows all the details so they can hopefully give you a proper diagnosis. One of the worst things about PCS is people doubting that there's anything really wrong with you, and a doctor's opinion can help with this.

Good luck!
