Pain....
horrible. Not the hip, but the incision and all those muscles and tendons that were cut. I actually screamed out loud the first time they tried to turn me a little. I was so embarassed. But the nurses were really good. But you know what.....it got less and less as the days went by. Do not hesitate to ask for your meds....don't wait till the pain is there!!! I actually had no pain while I was lying in bed. It was when they made me move; those horrid people!!!
Driving....I couldn't wait to drive. My doctor told me 8 weeks. But that's his standard time for lifting all restrictions. I was in my truck before that but he'll never know!!

I guess it depends on what hip, standard or automatic and you!!! My hip was the left and it's an automatic suv. The biggest problem I had was getting in!! That's where the running board came in and in the beginning the "leg lifter" I got in the rehab facility.
But remember.......
saftey. If you can not get in and out of your vehicle "fairly quick" then I'd wait. God forbid (and I hate to be morbid but this is life) you get into an accident and have to get OUT FAST...you want to be able to. You'll know when your ready.
