@Caesardust When do you start on Clexane and as @Charlie mentioned, you've got your compression stockings for the flight haven't you? On one flight back from CT I got terribly swollen calves, ankles and feet. I was wearing my stockings. It scared me actually and they took a few days to go back to normal. I've learnt my lesson. I'd definately try and get a handle on it before you fly out.What time is your lining scan tomorrow? Mine's at 10am.
