hi. this is in behalf of my friend. well these past few days she's been complaining of pulsating occiptal pains and i'm so worried for her. she's been lacking sleep, and her body clock is ruined. lately she has a habit of sleeping in the morning and waking up at night. she can sleep up to 12 hours! and even tho she's slept enough there is still pain at the back of her head. at present she said that the pain is triggered whenever she moves her head. at the same time it feels heavy according to her. i'm scared it might be aneurysm :( but i really pray not. what could be the other reasons for this? actually whenever she plays badminton she also experiences this kind of pain afterwards. what could it be?
