What Causes Fever Along With Chills And Burning Sensation In The Eyes?

Hello, I am experiencing strange symptoms, that coincidentally I experienced exactly 1 year ago. Last fall, for about 3 months, I broke out with a low grade fever every evening. It was always about 99 or 100, made me eyes burn and I got chills. I also experienced a slight headache each day. When I woke up in the morning, I was always gunky like I was coming down with a cold, but never broke out with one until Christmas Day. Both my husband and I broke out with a major cold and cough that same day. Our colds hung around for 3 months, and my cough hung on until June. My husband still has his cough. Now about 3 weeks ago, I began breaking out in the low grade fevers every single night again...around 7 or 8:00pm. I usually break the fever in the middle of the night and feel much better. But then when I wake up, I m gunky like I m going to break out with a cold any day. I ve never experienced anything like this prior to last year. I got my 1 and only flu shot about 4 years ago, and swore I would never get one again. So I know what I m experiencing now is not the result of having gotten a flu shot. Any suggestions as to what I m experiencing? I think I forgot to mention that on top of the fevers this fall, I m again experiencing a low grade headache. It covers both lobes of my brain, and is in the middle of my head....basically stretches from ear to ear. Most of the time it s not bad enough to really need any medicine. But I ve been getting these every day as well (any time of the day). Fever always comes in the evenings. Please help with possible diagnosis! Thank you!!!
