Hi, Mandy! Girl if you are in pain.... 15th sounds great!
As for "so many friends" etc. telling you the 26th? I am sure they are well meaning but please.
It might be about their own comfort... but I am sure they are well meaning just no one knows better than you and it's clear from you writing that "the sooner the better are you kidding?"
Tell your friends, hey I've decided about the 15th and hope you will support me and be good friends and fill me with happy thoughts, rather than too bad, so sad, you'll be recovering for Christmas. What are there a bunch of parties they want you to go to during that time?
Selfish. But be kind because they "know not what they do."
Traction at 13, body cast 1 mos., Milwaukee, first plastic (severe allergy, abdomen skin burst, watery) then leather. Harrington Rod @ 15, 9 mos body cast, hips up. 9 more mos being careful and protective. Degenerated disc C4-5 I think well above the rod. Degenerated disc below the rod now? Probably.
