Jeannine, I had both hips replaced in 2013, a month apart. Before the surgeries, the pain was crippling -- not the kind you can grit your teeth and get through. I spent several years in pain, because I had to be eligible for Medicare before I could afford to have it done. So, I went from a limp (one hip started to go before the other one) to a cane, to two canes, to a wheelchair over the course. I continued to work, and it was awful, the right hip collapsed and the socket was damaged. From what I've heard from doctors and others, the pain can pretty much strike anywhere on your lower body. Mine was mostly confined to hips and thighs and lower back.
Like Warri, I pretty much withdrew from everything except that which I couldn't avoid.
Getting my new hips was literally a new lease on life. I can walk again!!! I was in the hospital two days for the first hip and 3 days for the second one (that was the one with the damaged socket and was a bit more complex to fix). One bonus was that the surgeon lengthened one of my legs by adjusting the implant, so I am now free from having to wear big lifts in my shoes, which I'd had to do all my life. Now I can wear normal shoes with no problems.
My surgeon believes you should go home as soon as possible -- he says the longer you stay in the hospital or a rehab place the more likely you are to pick up an infection which can threaten the implant. He, and most of the surgeons around here, sends you straight home, and a PT person comes to your house to do a bit of PT with you. I live alone and was able to manage just fine by myself. The surgery instantly (yes, instantly) relieved about 90% of my pain. I actually cried with joy when they got me out of bed in the hospital. The recovery was uneventful, easy -- you just have to do little exercises, mostly geared toward avoiding blood clots, and NOT overdo. I had one glitch in that I had been unable to walk for so long that some muscles had lost tone, but that was quickly regained, and I had to learn to walk again without a cane (which I found surprisingly harder than I thought it would be -- it's getting the rhythm back, mostly).
I was back on my feet in about 2 months, overall. No marathons, but able to walk. I continued to carry a cane in the car, just in case, for another month or two.
If you are considering this, don't delay, and don't be afraid of it -- it really isn't anywhere near as bad as you think it will be. I was terrified about the first surgery and felt like I was going to the guillotine , but when when I got the second one a month later, I wasn't even worried at all.
It literally gave me my life back. I can do anything I want now, except my surgeon says no bungee jumping and no jumping out of airplanes. Also no long distance running on pavement.
