My grandma had back surgery and a stroke several years ago and today she's having a hard time standing up. are they connected?

Any othe symptoms?: Please take her to er to evaluate for any weakness in arms or legs or any numbness could be signs for recurrent stroke.

Needs evaluation: People that had a stroke are more likely to have a second stroke. Weakness is a sign of stroke as us slurred speech and facial droop. Better safe than sorry, take her to be evaluated by a physician as soon as possible.
