weak legs and not able to sit or stand

My mother started in 2009 with pain on her left shoulder joint, this continued slowly to difficulty in standing and walking. Was this due to pain or weakness?

she was given a treatment of vitamins which enabled her walk again, this was short lived because she fell on her back, but no injury seen on x-ray; her scan shows nothing but since May 2010, she has never walked again, she can not sit on her own, and when i try to support her to stand, its like her legs cant straighten.

Hello Cecilia,
When you say your mother can't sit or stand, is this due to pain in her or legs, or due to profound weakness of the muscles?

Is there numbness of the lower legs?

Seeing that vitamins helped I'm thinking of a vitamin B1 (beri beri) or B12 (pernicious anemia) deficiency.

If she has pain, then it sounds like a problem in her spine but you mention no back pain.

Big question: pain or weakness, what stopping her?
