MB292,

You need to slow down your life until things improve. You will improve but 13 years old is a challenge for concussions because the brain is being overwhelmed with hormones and changes in development. These put high levels of stress on the brain. Stressed brains take much longer to heal.

The amusement park was likely more traumatic that the single bump. The vibrations and jerking from the rides can be traumatic. You need to be aware of Sub-Concussive Impacts. These are head impacts or just head shakes that do not cause immediate concussion symptoms. They can cumulatively be as bad as a serious head impact.

So, slow down, reduce your risk, and give your brain quiet rest so it can heal. You should not be doing cardio or serious physical efforts until your symptoms get better. Ask if your school has a concussion recovery protocol. If it does not, tell them you need to be treated as recovering from a concussion. Have you mother or father write a letter demanding this consideration.

And, stay away from chemicals, no alcohol, energy drinks, caffeine, etc.

I lived through my early teens with serious PCS.

btw, How did you get your concussion ? Do you have a history of sports such as football or soccer ?
