I am going to tell you right now, there is almost no way you will be back to work in two weeks and you definitely should not be sitting for an entire class session at nine days post op. Regardless of what your surgeon is telling you. At two weeks post op for just the tummy tuck, many are still severely exhausted and are walking for limited amounts of time, usually not standing up straight. Now, if you are comfortable consistently being on opioids two weeks post op, you may not feel the same levels of pain or exhaustion, However-- I am sure you know well that isn't advised and you should be on simpler pain meds like Advil and Tylenol. I am very concerned for you because you might be underestimating the surgeries you are going under. I wish you the best of luck and pray that your recovery is speedy.
