Mail_man,

Welcome to NeuroTalk.

I am surprised that your highly regarded concussion specialist prescribed 30 minutes of cardio. That amount of cardio is usually not recommended until all symptoms are gone. Until then, exercise should be kept to a level that does not cause symptoms. And the recommendation to do school work is also not standard. Usually, somebody with PCS is told to reduce their cognitive load and take frequent breaks between study periods.

There is a key fact you need to understand. If you have seen one head injury, you have seen ONE head injury. No two are alike. The comment that you should be better in a month is just smoke. It has no medical basis.

There is no way you can return to LaCross and expect a low risk of another concussion. LaCross is a rough contact sport. You wear helmets because of the rough contact and risk to the head. You need to seriously consider whether the risk of future injury is worth it.
