We need more information. Is mom suffering from dementia? Is she in the home of the sister, or the sister living with her? Is the sister currently serving as the POA or the Guardian of your Mother? And most importantly, when you have asked your sister, or when she has blocked your admission to your Mom, what reasons has she given to you? That is to say, what has the "Lioness at the gate" so angry? Hoping to hear answers to the above so we can be of more help to you and sure are sorry you are going through this pain.
