Hi!
I believe you can rest assured that you are experiencing normal things post surg that will improve over time. Be sure to keep the lines of communication open with your surgeon and his nurse if he has one. Validate things with them as they come up as they are the experts.
It is scarey and you always wonder about it coming back but try to enjoy your health. Be patient in your recovery... don't rush it. I know that is easy to do. I would encourage you to talk to your family... they need to know honestly , how you feel...that is the best way for all of you to support each other.
Take care and best wishes to you.
