My grandma fell on the ground while using her cane. By the next day, she was in pain, her foot was swollen especially at the veins area. Also, whenever she attempts to stand up and puts pressure on her foot her legs begins to shakes uncontrollably and cannot move it at all. Also, she has an alzheimer, it may be irrelevant but it might be some connection to it. Did she forget how to move her leg? Maybe her neurons is not transmitting messages properly. I don't know. I am not knowledgeable about that area. Please help!
