Hi Rose,
I have been following this with dismay, as I also have seen (and felt) the indifference of Neurosurgeons to back pain.
While weight wasn't the major issue for me, the guy I saw waved his hand in a dismissive way and said I was not a candidate for surgery. I do have to say I was not dissappointed (I had been pre-warned by my PCP that my back could get worse if I had surgery).
I have a wonderful PMD and he is keeping my pain under control (I still have pain in the TKR knee).
One other note, I am not a nutrition expert, but 1,000 calories seems way too low for sustainable weight loss. Eventually your metabolism will slow down to conserve energy and weight loss will stop. Maybe consider something more like 1,200-1,300 calories/day. I am on Weight Watchers at about 1,500 cal/day with about 1-2 lb loss each week. Maybe someone with nutrition experience can chime in here?
Best of luck at your appointment today!
Sandy
