Keep riding, see your Doctor, ask plenty of questions, and don't hold back any info from him/her. Let the Doctor know you intend to go out and peddle, that will help determine what meds they give, some are not exercise friendly, while others are. Glad to see your are alright.
If your BP is high, make sure you get it treated, it is called the "Silent Killer" for a reason. I had not been to my Doctor for years, first visit for a physical to keep the wife off my backside about never going, and she said it was the only thing she wanted for Christmas. I spent 2 days in cardiac care unit at 42 years of age, transported via the meat wagon from the Doctors Office, they would not let me drive, nor would they let me leave under my own power, and I was not about to let them call my wife to come and take me, I would have had a cardiac from listening to her on the way. There is nothing like having every electronic gadget in the hospital hooked up to you, not being able to go to the bathroom without direct supervision (Why a female nurse can't help you is beyond me), seeing everyone else in there is twice your age, and everywhere you go in there they carry their jump starter waiting for you to need it. It is an eye opener. Try explaining to your 16 your old why you are in there, and trying to explain what you didn't do right in a parental fashion.
Take care of yourself, for you first, your family second. You can't take care of them until you take care of yourself. Good luck.
