Girls, hello, I previously wrote about headaches, for half a month they have been bothering me, now it started to hurt differently, lying or sitting normally, getting up and starts sharply hurting one hemisphere, then the back of the head and cheekbones, this is already unbearable, not even coffee, not paracetamol helps. Who had this? What could it be? Pressure measured, 110/70, in principle normal for me. Gynecologist I don't have at all, nothing says anything at all ? I think it's something serious.
