I can definitely relate to that feeling (limited concentration)! Thank you for your response. Mine very rarely results in a huge headache - just that feeling of pressure and pounding. If it's been particularly taxing - like 2 weeks ago I was preparing for a conference and so working at the computer programming/writing for ~12 hours/day all week - I will go to bed with it and wake up with it.

So far, I've seen 3 separate doctors. The first was a GP who basically said "you'll be fine in a few days. go back to all exercise and work except avoid contact" - fortunately, a knowledgeable friend told me to ignore that advice.

The second was another GP, who I've seen a few times. She seems relatively knowledgeable about concussions and actually has a son who went through this. She really pushed cognitive and physical rest (obviously), and ordered a CT after the first ~2 months. She also acknowledged the reality of my world, which makes cognitive rest very hard to come by.

Finally, I saw a neurologist. He did a host of neuro tests, said I had a mild concussion and PCS and was optimistic that by my next appointment I'd be doing much better (that appt is in 2 weeks).

GP2 gave me low dose amitryptiline, and Neurologist changed it to nortryptiline because the first med made me really drowsy in the AM.

My neck has not bothered me at all.
