Thank you for both of your responses.

I did go see a neurologist about a week after the concussion and was told that all my symptoms were normal and to just give it time. What I am afraid of is that the doctor will just blow it off as normal again. My insurance is terrible and has a high deductible. I think I spent $700 just to see a specialist last time.

Icing the neck is great idea as i have noticed some stiffness. However my main problem even when I was getting better was the headaches from work on a computer/TV screen. After too much, I would have a lingering numb headache for the entirety of the next day. Which would go away depending on how much sleep I would get. This numbness would also cause me to be extra aware of my speech as It felt as if I needed extra effort to speak correctly without a slur. But this was the first time the physical exercise caused a set back. So now i'm worried to do anything outside. Run, yard work, etc.

What can a doctor do really? And is it worth doing a follow-up? Thank you all for your responses.
