<human>: The last two nights after eating supper I came down with the chills, then turned into a bad headache and fever, followed by sweating. Both meals were different and feeling ok during the day. Doesn t feel like I m getting a cold, so its becoming kind of scary. I was sick with a head-cold / sinus infection within the last two weeks, but have been taking antibiotics. I m on my last day with no symptoms of relapse. It was a pretty bad cold with a lot of infectious saliva, but that has cleared up. Please help out, I will be making an appointment in the morning, but would like help to get some clarification right now as I sit here sweating.
<bot>: Hellos you mentioned that you are feeling chills, fever and headache, particularly in the night even after different meals on both occasions. So this type of fever may be due to :1 Throat infection or pharyngitis, as this is the most common cause because 2 weeks ago you were having sinus infection, so may be the reason of such symptoms .2 Urinary tract infection may be the another reason of such symptoms. Get in urine examination for any infection.3 Typhoid fever may be the another reason of such case. At present, you are just going to consult a doctor, so take Tylenol for fever. However, there are so many other reasons of such symptoms, but respiratory infection may be the most probable.
