A chat with the doctor's nurse and the diagnosis of of osteopenia. Osteopenia is the first stage before osteoporosis. Osteoporosis is when you break bones by falling.
I fall now and then but it's because of peroneal nerve entrapment. The peroneal nerve lifts my toes. Without its help I trip over microscopic roots or branches. I trip because I don't feel my toes failing to lift themselves. But there's no way of arguing the point with doctors. So now I start vitamin d and calcium. On top of the dozen of meds I'm already on.
Doctor Google says weight-bearing exercise is good for osteopenia. I have a treadmill and walk/run three times a week. I can set the incline to 15% grade. That definitely turns it into a weight-bearing exercise.
I've got a constant mild pain on the underside of both patellas. Is this related to osteopenia? My 40-year weightlifting history tells me a little pain is a good thing. It's only a problem if I need pain pills to be able to work out.
