I don't know why you'd feel "agitated" after exercise, but I do know that exercise raises the blood pressure during and for a short period after the exercise. (we know it works to lower BP over the long haul, though) I also know exercise revs up the metabolism. And I've read that you shouldn't exercise right before bed. So maybe what you're experiencing is normal for you. You're not having any irregular heartbeats or chest pain?? You can always call and visit with your doctor on the phone and see if he/she is concerned enough to have you come in for an evaluation.
