I am suffering from fever since last three days,may be cause of central AC in my office , but I had a severe headache too, now the fever is almost fine when I don't sit under fan or ac. But the headache is not going away,when I sleep calmnly at night  in the morning it's all fine , but if I watch TV or mobile for few minutes, severe pain starts again, my toilet is also not that clear, today I was traveling in metro and suddenly I felt severe headache and stomach pain that I had to get down to another station and had to sit on chair for 15 - 20 mintues and was sweating a lot ,after few minutes I was normal . Is it a chance of getting spects on, I don't wear any . Please help me. Thank you
