TZ,

Welcome to NeuroTalk. It sounds like you may have mild PCS. Have you read the Vitamins and Supplements sticky at the top. It will help your brain tolerate stress.

At your age, the brain is in overdrive as it matures and deals with changing hormones. Any stress to the brain can easily be magnified.

If you want to exercise, start slowly with a short activity to see how your body responds. Wear ear plugs so you can learn a foot plant that does not jar your head. You may have a subtle neck injury that plays a part in your head aches. Jarring from foot plants and poor resting posture can make even a very subtle upper neck injury into headaches.

With good brain nutrition and proper care of your upper neck, you should see improvements. It will take some time but it is worth it.

My best to you.
