i'm 15, over the past 4 days i've been experiencing headaches i've never had before. it's like quite a sharp pain mainly at the front of my head but the back and sides of my head have this wierd faded pain. it literally comes and goes, sometimes it's strong and hurts when i move my head, sometimes it goes and it feels like i don't have a headache at all. it kinda feel wierd when i'm laying down too, it's like a really faded headache. can someone explain this to me. been happening since thursday morning when i had a nosebleed and a few hours later i got the headache. my anxiety and depression are changing me so please answer and help me out ! apologies for any typos in this, hopefully it's clear enough.
