@lenzo I hope things go great with your hip replacement. I know two people who have had them within the last year and both of them have done great. They did not have peripheral neuropathy though, just arthritis in their hips.

My brother in law was back taking long walks with my sister very shortly after the THR. He is somewhat thin and I think that helped, not having any extra weight. If you are overweight at all I would suggest trying to lose a few pounds between now and May. I know, it's not much time, but every little bit helps.
