Hello NCGuy,
Welcome to the NeuroTalk Support Groups.

You should perhaps repost over on the
Traumatic Brain Injury & Post Concussion Syndrome Forum

It's not unusual for CT and MRI to be clear. The other symptoms are fairly common and it's still early days with it being only 4 weeks since the injury.

Check out the "Sticky" threads at the top of the forum too if possible. There is a wealth of information in those threads that may help you on the road to recovery.

take care.
