do i have 2 legs and trembling

[KG1993]

Mom had gamma in Feb. She just had MRI 2 weeks ago and spinal tap because she was having trouble walking with one of her feet.

Scan showed no progression and spinal tap was free of cancer cells.

TODAY while I was visiting she asked me why she only had 1 leg.......

she also has tremors in her hands occasionally.

She mentally is good on other things, but then out of the blue she will say weird stuff.

Any thoughts?
