My friends' headache

Lately, my friend has been having headaches when she leans over .They are on the left side of her forehead . She also has nausea. S he went to a doctor last week and doctor is making some test to find out what is causing there. He told her to rest and stay away from bright light . He gave her some medicine to help the nausea. I keep reminding to turn the light down and to take her medicine.
