I try giving pain pill but she is not eating or drinking well. Sometimes I check on her and she starts laughing and other times she is holding her hip. I put her in chair and try to position her comfort and I do try to position her bed.. this started a few days ago and I'm at a loss.
Has she had it imaged?
My 100-yr old Aunt with advanced dementia needed assistance to walk. One night out of the clear blue sky she decided to shimmy past her bed barriers to walk somewhere. She fell on her carpeted floor and broke her hip high up by the ball. Outside of surgery (which I declined) there was no fix for this.
I agree that if she isn't an appropriate candidate for diagnosis and further therapies then hospice and palliative care may be the next best option for her.
Speak with the doctor about what you are observing. This may be a matter of doing the best you can. Be careful of heating pads as elders burn very easily and as a nurse I saw any number of minor burns from them.
