What a wonderful report on your second hip!! Congratulations on your approach to recovery. You are living proof that our BoneSmarties recommendations really do work and we love hearing that.
If you have a pool, even though you might not be able to do laps, you can do water walking or, if it’s deep enough, water cycling by sitting on a pool noodle. Both are gentle exercises that are good for you. The water gives you extra support in the early months of recovery. Just be sure to build up slowly because it’s easy to overdo things in the water. Perhaps you could put that darling grandson in a floatie and push him around while you pool walk.
