Hello, Severe headache on and off for five days. About two days ago, my left temple, in between my temple and ear, a little higher actually will throb/pulse pretty intense. Especially when she lays on her left side. She is also experiencing quick on set of sever head pain when she moves from a sitting position to a standing position. I am asking this for my daughter, as she is unable to stay contacted to the internet. She was able to get online for a bit and saw something about annurysms and it scared her. She is 21 years old. Do you have any idea of what she may be experiencing? Thank you.
