Hi Liz
Welcome to Hip Talk.
I am not medically trained, but did have my hip resurfaced in March 2006 with Dr. De Smet of Belgium. I have done a lot of reading about hip resurfacing and belonged to the large Yahoo Surface Hippy Discussion Group of over 6000+ members
http://health.groups.yahoo.com/group/surfacehippy/.
So I can give you some answers for your questions based on the things I have read and my experience.
1. The distance or amount you walk really has to be up to how you feel and how your new hip feels. I was walking almost a mile a day with one crutch at about 15 days post op, but I only had a hip resurfaced with no other special problems. Dr. De Smet always tells his patients to "listen to their body" If you feel really tired or sore - you walked enough. You do have to watch that you don't "hit the wall" as one of our Surface Hippies, Alan, use to say. You feel so good that you go out crutching and walking - but then realize you all of a sudden are tired and wonder how you will get back. Pace yourself and don't do more than you know you can do. You have plenty of time to heal and walk in the future. Your recovery won't be any quicker or better just because you walked twice as far than you are doing now.
Do what feels best for you. You don't have to push it. I was able to put all my weight on my leg and used one crutch until 4 weeks. But we are all different. In the end, we all end up in the same place - we have healed hips that don't hurt that allow us to do anything we want. We just have to have patience until we get healed. Healing actually takes a whole year or more. Usually you feel healed and can be very active before that, but inside your body is still healing.
I was lucky and did not have swelling. But many people do. Usually it is because you have been too active. Sometimes it also just happens as the result of surgery. Everyones body is different.
Many people ice their hips to reduce the swelling. Some doctors acutally use fancy ice machines that pump cold water thru a tube to a device on the hip. But just a bag of ice works well for many people. Some people have used large bags of frozen peas because they mold to your hip shape. Just don't eat the peas after if you keep refreezing them.
Also resting helps reduce the swelling. Dr. De Smet always said "toes above the nose" to keep swelling down. If you are laying on a bed, put a pile of pillows under your legs to get them higher than your head. I always slept that way for a few weeks after surgery. If you have a fancy lounge chair - you can sometimes get your legs pretty high.
Dr. De Smet's PT sometimes just had people take a day or so off and just rest to get swelling down. You need to experiement to see what works best. Using ice and getting your legs up will probably be the best.
You might want to call your doctors office to see if they have any additional suggestions. They might suggest that you also take Ibuprophen since it is an NSAID (non-steroid anti-inflamatory drug). That is an over the counter drug here in the US.
So my best advice is:
Don't push yourself too hard - you will have plenty of time to do that later.
Ice your leg and lay down with pillows under you legs to reduce the swelling.
Good Luck. It won't be long before you will forget all about the surgery and the healing.
