Hello this is actually for a friend of mine. She was having a very bad headache since saturday night and had taken a few painkillers and sleeping pills which she later had found out it was expired. She threw up after that and had felt a slight abdominal pain before vomiting. Yesterday in the afternoon she had a headache again and felt abit dizzy and got it again in the evening. Pls tell me what I can tell her to do. She was having a bad sinus infection before and finished her course of medicine a few days ago.
