It's great that you are exercising, but in general, you do want to take it easy for the first 5-7 days after eyelid surgery. The reason surgeons ask patients not to exercise during that first week, is that it increases the risk of bruising, swelling and bleeding behind the eyes. All patients get bruised and swollen after eyelid surgery, but bleeding behind the eyes is a potentially serious complication that we are all trying to avoid. In healthy patients who don't have high blood pressure and aren't taking blood thinners, the risk of that issue decreases dramatically after about a week. So that is why we say you can resume exercise at that point. Of course, you should discuss this with your surgeon, because each patient has different medical conditions and even over-the-counter medications like Advil and MultiVitamins can affect bleeding.
You should follow your surgeon's post op instructions. Different surgeons follow different protocols and there is variability depending on the procedure.
