I have been getting a large amount of severe headaches in the large 6-8 months. But the last two have made me sick too. I can bearly focus when I have a headache and have to lie down. I feel tired all the time, even if I have just got up. I can fall asleep anywhere and fast too. I feel odd and like I'm not really here(if that makes any sense) and I have hearing loss too (i had a hearing check and I have some loss) Could it be to do with my brain or is just migraine?
