You are 1 week post-op now, so you should know how your own personal recovery is coming, at least compared to other patients your surgeon may have cared for. Ask his or her nursing staff. Let's assume your drain(s) are out and things are healing well. I'm sure your surgeon has outlined various restrictions for you such as avoiding strenuous activities, lifting, and certainly nothing like sit-ups, crunches, jogging, etc. These all have times when they are allowed associated with them.
Your first day back at work may be quite taxing, depending on your type of work, your required pace at your job, the stress you encounter after being gone for 3 weeks, etc. Many of my tummy tuck patients return to work after 1 or 2 weeks; usually, having their drain out so they can shower and wear normal clothes is a prerequisite for even sedentary desk jobs or clerical positions. Standing all day at a hair salon, working at a bank on your feet all day, or any number of other high-level, supervisory, or physical jobs will each have their own requirements, stresses, and take their toll on your ability to get through your day.
And then you want to go to a concert!
Is this a classical piano concert? Or a heavy metal band with a mosh pit and lots of illicit chemicals in use? A rave or a high school band concert? You know what I mean!
The real answer is probably known to you already, and even more accurately if you ask your surgeon while providing those little details such as what kind of job you have, and what type of concert you are attending, and just how your own recovery is coming along.
Feel the Force, listen to your gut (and your plastic surgeon), and don't risk messing up your $8000 operation! That being said, if your surgeon agrees and you behave yourself, have a great time and give yourself a day off to rest up afterwards! You may need it! Best wishes! Dr. Tholen
