Swollen ankles and feet - help or advice?

I'm 32w 2d and still traveling for work. I have two trips left and currently can't really get my ankles to look normal. I'm drinking TONS of water, trying not to be on my feet for extended periods of time, and soaking nightly with Epsom salts and essential oils (lavender or peppermint). I'm also icing my ankles because it feels good in this heat! My husband is being wonderful and giving me foot massages too.

Any other things I can try? I have two trips, one with a short flight of about 2 hours, but the last trip is a 3 day back and forth to the east coast (I'm on the west coast so long flights - about 6 hours

). I'd really like to be able to wear normal shoes and appear professional! Once I'm back in the office I can be more casual.
