My nan is back in the hospital

My nan woke up today saying she was seeing "red dots". She had a doctors appointment at 10:10 this morning. Well my sister called me around noon time saying that she was taking my nan to the hospital again, they thought she was having a stroke. I really cannot believe that this is happening. Again. So please, once again, keep my family in your thoughts and prayers, especially my nan. I really appreciate it :)
