Who's giving the massage? An Elephant?...internal bleeding!
But at 6 months? He would have been advised to not sleep on his stomach as well then.Maybe the doctor doesn't want you to put any pressure on your sternum by lying face down.
Advisable to do Back Massage (face down) after six months of avr?
Well, I guess I should have been more careful in reading the OP's post! 6 months is a long time to still be concerned about damage to the sternum. But then why did the doctor seem reluctant. I think you need clarification on that.
