My sister is 61. She recently was watering her garden outside after coming home from work, She woke up on the ground, She does not remember being dizzy or falling, she hit her head and has a bruise above her eye. When she woke up family members asked her questions. Some of her responses were clear, much waw gibberish. She does not remember any of the conversation. At least 2 other times she found herself on the floor, not remembering she lost consciousness. Prior to this, she woke up sitting in her closet after she had gone go bed. Does not remember getting out of bed and has no idea how long she was there. I obviously strongly urged her to see a doctor soon. She doesn t have money right now to go. Can you please list some possibilites of what she might be experiencing. My thought was a stroke fo throwing a clot. I know it must be something very serious.
