So, since last night I've been feeling like a headache. I didn't worry last night because it just lasted some minutes and I went to sleep, but today, it was really weird. Every time I did like a sudden move, it would hurt on both sides of the head, or when I got up so suddenly too, or if I just laughed, also out of nowhere. I took Ibuprofen and it seems that the pain is fading a little bit now, my question is, do i need to be worried about this? Or is just a common thing that happens sometimes? I'm 18 if that's necessary.
