Last night i got a really bad headache, well it was more like strong stabbing pains in my head, i went to bed, but i felt like i had sea sickness. So ended up in the toilet for ages being sick, then i started sweating and burning up so much i had no clothes on then all the windows open. eventually went to sleep woke up at 8am this morning. Felt not too bad when i first got up, but slowly im starting to feel ill again. My eyesight is a bit bleary and when i stand up feel like im sea sick again. Any ideas on this???
