About a few weeks ago my Grandma found out that she has Congestive Heart failure. The doctor gave her some medication and told her that it was nothing serious. I believe that nothing bad will happen to her, but my mom is extreamly worried about her, she thinks something bad is gonna happen to my grandma. My grandma takes her medication. Her blood pressure is good, but her ankles swell up a bit from time to time. Is this anything serious that my mom has to panic about? I m trying to tell her that everything is gonna be fine but she doesn t believe me. What can I tell my mom to convince her that my grandma will be alright? This all started when my mom s sister told her that someone she knew had congestive heart failure and died because he never took his meds. But I know that my grandma will be ok. The doctor even said she would still live for a very long time. Any kind of input would be greatly appreciated. Thanks.
