MFOR, there's always a way back. In 2012 I had a hip replacement operation and was told not to attempt to run for 6 months. One doctor even told me not to run at all. I made a full recovery and exactly 6 months later did my first post-op run. On 11 January 2016 I had my other hip replaced and will finish 3 weeks rehab on Monday. In July I shall start running again, on that you can depend.
