My doctor says it is arthritis, and it it may very well be, but .... since I retired in 2012 or 13 ... I have spent HOURS at this damned computer ... reading, reading and reading and I'm inclined to think;
I have atrophied my lower back muscles to the point where walking is a painful experience.
That little short clip looks a lot like me when I force myself to walk "beyond the pain" (in an attempt to try to rejuvenate my sore muscles), and the truth is ... I can't WAIT to get to where I can sit down.
Sitting is a comfortable and less painful position, even more so than lying down in bed.
Anyway, that's MY two cent's worth on the matter.
I don't know about the coughing but IMO, she's been sitting for years and CAN'T walk or be normally ambulatory.
use it or loose it
I wonder if she's a closet smoker? Having been around family members with COPD just about all my life I know they can't walk very far without having coughing fits. They start out with the hack that gets progressively worse over time and walking aggravates it.
My doctor prescribed Meloxicam 15mg for inflammation. The stuff is like magic. No Pain.
