Not knowing the history, risk factors and the type of treatment you are on this question is best left to the physician. Unfortunatly in today's society the lay person must become an advocate for their health care. My suggestion to you is ask the physician boldly and firmly what you are and are not allowed to do. You cannot ake it upon yourself to try and do things that mey be CONTRAINDICATED.. If you do further problems can arise. I hope this helps you, but please talk with your doc, as no one knows better than him/her when it comes to what is best for you. Sorry I could not be of more help.
