Hi I am a Paramedic with PCS. I don't think it will effect your ability to go to school and depending on severity of symptoms it may not effect your ability to get a job. That being said 2 pieces of advise. 1. Definitely tell the truth about the PCS symptoms it not only effects you in the field it can effect you your partner, your patient and anyone else involved it your calls. 2. Make sure that you take into consideration that working in the back of the truck takes a lot of balance concentration and is physically demanding it put s you at risk for more concussions which for people like us can have effects. I am not trying to be discouraging but think you should understand your risks.
