If you haven't ever shaved your chest before, beware! I did it once years ago and the itching as it grew back in was so bad it kept me awake at night. And that was with nothing stuck to my chest. For me, having the hair grow back under the bandages would be torture and the itching caused by the bandages was bad enough. You might even get ingrown hairs. I think this is why they don't shave the whole area at the hospital. A few moments of pain is better than days of itching, IMHO.
Did anyone here shave before going in?
