Keep her in your thoughts....

Doug, I have ankylosing spondylitis, and it is crippling if I lay around and do nothing. I'm not sure about her other problems, but I can say for sure that it's absolutely necessary to be active to not be in pain from ankylosing spondylitis. It has rarely bothered me for years, since I figured out that keeping active keeps it from hurting. Humidity and cold also cause it to flare up, but I've been in Southern CA and Arizona for the past 18+ years.
You really need to try to convince her to get up and move around so she doesn't lock up completely.
