I need you opinions and advice. Almost 3 years ago my mother died and it's always been on my conscience that medical mal practice was done. My mother was in her 60s and her medical history was she was diabetic,had high blood pressure, anemic, due to microscopic blessing in her intestines, as well as had thrombocytopenia. She would frequently go to the hospital for blood transfusions because she would become so anemic. On one particular occasion she was admitted to the hospital and given 6 units of blood. Not sure if Lasix was given between these transfusions but stayed for some days then discharged home in a Saturday. On that Saturday I believe she told me her blood pressure was high which isn't a surprise but that day I believe it was in the 170's. The following day she had a hemorrhagic stroke and later died....😢 the reason I wanted your advice is cause I've always thought thay they discharged my mom home from the hospital with an extremely high blood pressure and I feel that is what caused her to have the stroke the following day. Am I wrong in feeling this way? Advice please
