She scoots around the house in her wheelchair, refuses to use the walker.
However, she gets up and down to go to other rooms, and the bathroom, etc.
Also has no appetite. I'm at a loss as to what to do? Doesn't look like she's in pain.
I'm afraid she's giving up!
What did the x-rays show of her knee injury? Have you contacted the ortho doctor to get his/her opinion? Does she have osteoporosis, and are you in an area that's had either a very rainy episode or is getting colder?
My SIL suffered right-side paralysis after a series of small strokes following a ruptured cerebral aneurysm. Although she was able to walk and sometimes used a crutch, but she was slow and felt unbalanced. She "rolled around" through her home in an office chair. She could move faster, carry stuff on her lap, and didn't feel like she might fall any minute. She would also get up and walk into the bath or to retrieve something she couldn't reach well from the chair. She would roll over to the kitchen sink or the washing machine to do tasks, then sit down and roll away afterward. Her young grandchildren liked taking a ride on her lap. It worked for her.
Only your mom knows her own pain. You think she's faking? To what end?
Try to talk to her to see what she plans to do. Maybe she's wanting surgery and trying to 'fake it' so to speak, until some dr agrees. That's not outside the realm of possibility.
Getting old hurts, sadly. Sounds like she's trying to find a way to be mobile on her own terms. At least she hasn't taken to her bed and refusing to get up.
Wishing you both the best of luck.
What is mom's health status now? Has she ever had PT to strengthen her? Does she have a diagnosis of dementia? Is she living with you or you with her?
Updating your profile would be helpful.
I think her scooting around in a wheelchair is helping her to feel safe and may actually be safer for her. Maybe PT is in order. Have a chat with her doc.
