I've had a headache behind my left ear since last friday (13th) and it's been pretty much constant. At first I thought it was because of the newly bought sunglasses I was wearing on my head causing pressure so I took them off, however it continued. I was given glasses a few months ago but I stopped wearing them after a few weeks as they gave me a headache and they were only because I'd need glasses in the future. Thinking this could be a cause I started wearing them again which didn't help.
I've been drinking water and taking tablets but the pain is still there, sometimes it's a dull ache and sometimes it's quite sharp. I'm 17 years old so is it something I should be worrying about?
