... and I don't know why. Neither does my doctor.
I was 5'8.5" in the Army in 1968 and I'm now 5'5.5", 40+ years later. I'm losing almost an inch a year, beginning four years ago, when I was first measured at my doctor's office. I hadn't lost any height until then.
If I had compression fractures in my spine, I'd have pain. No pain. Maybe osteoporosis. But no chemical traces suggest that, nor is there any bowing of my back, and it's rare in men anyway. X-rays are next.
WTF?
