>>I am beginning to think that by the time the pain is gone, I am going to have to go to rehab to get off the pain killers :(
Call your surgeon and calmly lay out what you just said here. Your surgeon knows how your operation went and wants you to have a successful result so if you're not feeling it, you need to work together to figure out what to do next. If the advice is to stick it out a bit longer- then it's not what you want to hear, but it does take time for uncemented prostheses to settle. In exchange you expect an outcome profile that you can enjoy for years to come...
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
