Breast Reduction - Leg Elevation During Recovery
I think you have to be concerned with doing a lot more than that. Combining these procedures, particularly if being done under general anesthesia (as is likely in view of what you're having done) is associated with a risk of blood clots in the legs (referred to as Deep Vein Thrombosis, or DVT). If these break off and travel to the lungs it is called a pulmonary embolus, and the results, in that case, can be fatal or, if not, can cause significant morbidity.
You are right...
