How much swelling is normal following anterior hip replacement surgery

I am 5 days out from anterior approach hip replacement surgery and my entire leg is very swollen. I had a neighbor help me put on my compression knee highs that I had but that seems only to have pushed all the swelling up towards my knee and above. I have been icing as much as possible and walking fairly often. When I am in my recliner I try to have my head back as much as possible so my legs are raised. I live alone and don't even have my first visit with home health until Tuesday; today is Sunday. I am afraid that if I can't get this swelling to go down some I will do myself some kind of harm in not paying more attention to it.
