Is this a hormonal thing too? I've had three periods since having had my baby and have experienced a little discomfort down there as if i'm a little swollen at these times??
Katkins, keeping off your feet is a great suggestion... Also when you sit (and you're not around polite company, LOL!) I find it helps to 'sit like a man' (with your legs impossibly far apart), and take up the whole chair!
