Update on Grandma:
Grandma is still in the hospital, and still in a great deal of pain (some days are better than others).
She is wearing a neck brace to keep her neck still to allow the fracture to heal (surgery is deemed too risky).  This could mean up to 3 months of limited mobility wearing the brace.
She will be moved to a long-term care facility if/when her pain is manageable and her nutrition is balanced out. (She has no appetite.)
Mom has stayed with her ever since the day of the fall. 
My sister has been there every day.
I'm going to visit her again tomorrow.
Thanks for your prayers.
