have had pain in my head for about 10 days now, its not excruciating but its always there. one side of my head, sort of behind my eye and towards the top of my head, quite a sharp pain, gets worse when head is upside down. i am getting a cold but wasnt when it started. cant find anything on google, does anyone think its a migraine or something? have never had a problem with headaches before, dont have a lot of time to go to doctors
