Ayoosh,

Welcome to NeuroTalk.

First off, you suffered a concussion. Unless you had a CT Scan that showed bruising on opposite sides of your head, calling your injury a coup contre coup injury is just speculation. Don't let that term define your injury. Bouncing back and forth in the car is not a coup contre coup injury either. That is just multiple impacts.

Regarding your speech struggles, many have different levels of speech dysfunction. If you developed these problems a day or 2 after the injury, you should be seen by a doctor. RIGHT AWAY if this speech problem continues or gets worse.

It might indicate an injury to your speech motor control system.

Until you are seen, ice your upper neck. The 10th and 12th cranial nerve controls the tongue. It comes out of your upper neck. If you have any difficulty swallowing, these nerves would also be suspect. I suffered damage to these nerves and it primarily impacts my ability to swallow.

Inflammation in your upper neck could be restricting function.
