Could Numbness In Hands Be Due To Hypoglycemia?

my mother is 73 year old type 2 dm for 10+ years controlled with oral meds with A1C always around 6.2-6.6. in march she went to the hospital with a respiratory illness for 4 days. upon returning home she became progressively weaker in walking and also her upper arms, she c/o numbness to her hands and now needs to use a walker and have assistance to get out of chair donne and doffe clothes, and holds cup with 2 hands and has difficulty wih her fork use. prior to the hospitalization she was independent and even quilted. she has had c-spine x-ray-neg, abdominal ultrasound-neg, emg of ble showed poor circulation. she will have emg of bue in the next week or so. noone seems to know the cause of this sudden dramatic decline. There is no change in mentation and all facial movement etc is symmetrical. does this sound like the effects of hypoglycemia or something else
