Hey Pat!
Good luck with your surgery! I will keep you in my prayers and thoughts. I think it will go well with you. Good advice...be diligent & tough with getting up and walking as soon as you are able! It doesn't feel good but it IS good and will get you back to normal living more quickly...of course I know there's a bit of a rebound time with AS too. Be hoping for a quick return and soon hearing an "I'm ok!!!"
