Theresa:
Elevating the legs, massages from the toes upwards to the knees may help with any discomfort from the swelling. (I used to do this with my husband Tom when his feet and legs swelled) Compression stocking can also help (Walmart for about $20)
Also some medications can also help as Marion mentioned. Paracentesis is a simple procedure for fluid in the abdomen but your husbands doctor would have to order it.
ASK QUESTIONS! Your husbands doctors should be able to answer them.
