You might try the PerfectSlim Pro-Massage (the one with roller) from L'orXXX which is available from any Health & Beauty stores. You can use its rollers to roll on your legs after bath daily and it works for me so far (as I'm kind of person who have swollen legs most of the time even before pregnancy). You don't have to apply the gel it contains afterwards if that concerns you (it contains Caffeine)
