Facial Swelling

Does anyone have any help for facial swelling?  I am in month 6 of Avastin, Alimpta, Carbo.  Take Dexamethasone for 3 days every 3 weeks (day before, day of and day after treatment). Each month it is getting worse, along with abdominal swelling - any suggestions would be appreciated.  Already cut out salt and drink lots of fluid (which I don't seem to be shedding).  Hope to hear from fellow survivors.
