I would like a dollar for every joint replacement patient who wrote, "assured I’D be up and walking and we’ll recovered but 6 weeks..." - I would take a trip to Hawaii!
Please read this message, which I wrote last night after reading it for the 3rd time just yesterday:

25 years ago, if you had your hip replaced, you would only have gotten home from the hospital a day or two ago. Your stitches are still in your leg, your bone has been sawed and pounded, and you lost a lot of blood (that's the swelling and bruising you see.) Bones, nerves and muscles need to heal, your blood volume needs to return to normal, and you need to rebuild your strength. Today, in our instant society, there is an illogical expectation that nature no longer rules, and somehow we can speed up that process.

As for "I try to elevate it, but been told to rest is to rust..." True, to a point. You do need rest to heal, and that alone takes at least 6 weeks. Also, as long as the swelling and bruising is there, when you are seated, elevate that poor leg and ice it as much as you can. I went back to (office) work at 4-6 weeks, after both knee and hip surgery, with my trusty ice packs, and kept my leg propped up unless I was up walking around. But, that also means to get up and move - 5 minutes or more every hour. Do your PT exercises every day - twice a day - for several months. And walk, walk, walk...

I hope this encourages you to understand that what you are experiencing is normal, and that if you allow your self time to heal, and do your therapy, you will have a happy result - it just might be more than 6 weeks.
