Oh my aching back

I have been having alot of trouble with my back lately.  I've been to the doctor, orthepedic specialist, physical therapist, chiropractor.  The only thing they can come up with is sacariliac joint dysfunction in my hip.  There are days when I can barely get out of bed.  I guess it has been on Rachael's mind because the other day in the car she asked me how my  back was doing.  I thought that was so sweet of her to ask.  I had actually been feeling better.  Rachael asked if it had been bothering me much lately.  I had to ask why she was so concerned about it....  She said it was because when she was at school in the gym playing with her friends they had been playing step on a crack break your mothers back.  Rachael then informed me that she told her friends not to play that game anymore and she was wondering if that made my back better.  I thanked her for thinking of me and informed her that that was very nice of her to stop stepping on the cracks for me.
