The fear of the unknown is normal, but you have to realize that the outcome is totally out of your hands. Trust your surgeon, and the other qualified, caring people who will be taking care of your husband from the time he arrives at the hospital. Believe me, they really do care about him doing well in the surgery, recovery and the subsequent healing process. They will do everything in their power to make sure his surgery goes well, and he is taken care of in a professional and caring manner. Try to verbalize the reason for your fear, and do your best to resolve it. Just trust your health care professionals to do their jobs. They know what they are doing, and they will do it well. Pray and trust God if you are a person of faith, and if not, lean heavily on your friends and family - they are all important to you at this time. Again, my thoughts and prayers are with you.
