Headaches for 5 months. All my head hurts day and night feel very tired even when I ve just woke up. Feel pressure in my head all the time dizzy alot. It s worse during night and I shiver. The other day I could hardly see anything because it was so blurry but when I shut my left eye I could see again. It frequently turns in to a migraine. My doc doc gave me 3 lots antibiotic antihistamine but nit helped. My leucocyte and other bloods are raised.i can t stand pain head
