A doctor who was speaking at a myeloma conference I attended said “the very best thing you can do for your bones is walk.” This in the context of very weak bones, vitaminD deficiency and osteoporosis. The act of putting your weight down over and over stimulated your bones natural strengthening process. He said take your bone strengtheners if you need them, make sure you have enough vitamin D, especially if you live in the northwest, and walk, walk, walk.
My husband found that walking was the best medicine for a lot of things. I find that I have a lot less bone pain if I can get out and walk a bit. When I read your comment about getting some exercise, it made me remember how beneficial it is for people who cannot lift, push, or pull anything.
I also find it helps my mental health to just get in the habit. It certainly has helped us in dealing with life threatening illness.
I am thinking about you, please keep me posted.
