Kidney stone. Having been through the exact same thing recently I certainly understand how much pain she's in. Her sister is at home with her and I am running her errands, picking up scrips going to the bank etc.
If you have her phone number you may want to wait a little before calling her.... she''s way out of it on pain meds right now.
She doesn't like to be taken care of, but she will be until she's feisty again.
