Perhaps different surgeons have different protocols. Mine was Dr Schaff in 2022, I had no shots in my stomach to prevent blood clots or anything else. I did have to wear compression stockings for a time and that was annoying but OK. I did develop blood clots about 2 weeks after, was home, walking and moving often, do not know of those stomach shots would have made a difference. I did take Eliquis for about 5 months after they were diagnosed. My home cardiologist was "right on it," we have no COEs around here.
