A month before, i started having headache..it was persistent and i got no relief from paracetamol then i went to eye doctor for check up then she said there is infection in my eyes and has given me eyedrop and also got specs..then after some days my headache started slowing down but still was there so i went to the doctor then he has asked me to continue my vitamin d tablets as my vitamin d level was very low in my previous blood test and he has also given me napra d 250 and asked me to take it whenever i experience pain..and also says if it persistent then he will do a ct scan..now I'm terrified as my headache is still continue..so what will come in the ct scan..( my headache usually happens in left back side of my head and sometimes also in right and sometimes in my neck) and i also have bad habit of sleeping on double pillow and also my sleep pattern is very wrong as i sleep at 2 or 3 at night and i woke up at 11 and i also have anxiety and i take too much stress
