Hi Hoppie,
I don’t worry much about a revision. My quality of life is very important to me, and running is a key contributor to my quality of life. It’s been 9 years since I got my hip replacement and I am still going strong. We are all a big experiment. I hope you find solace and support from us. Don’t ignore the doc, but be sure to question the recommendations and see if there is some wiggle room for you to test the hip by running a little.
