I think you should go in if your pdoc is all for it. And if you do decide sit down with your son prior to going in and have a talk with him. As far as work goes I totally understand. I actually started a thread about keeping a job. I think if you have something from your pdoc stating the time off you need there is nothing they can really do about it since you are following medical advice. Also, mindset yourself that in order for you to be the best at your job you need to take the time to take care of yourself. A good employer will understand.
