Yes, I do have this happen to me. I had this happen and then I developed a really bad kidney infection.
The doctor explained it to me this way...*While chills and fever often come together, they don't necessarily have to. Chills are caused by your body's attempt to burn energy and increase your body temperature. This happens usually when your body is trying to fight off an infection. Thus, chills assist in causing fever, but often arrive first before your body temperature actually goes up. If you felt normal the next morning, then either your chills were not the cause of the infection, or your body may have fought it off. Another cause of just feeling cold include hormonal deficiencies such as hypothyroidism (not having enough thyroid hormone). If you continue to feel cold, you*doctor*can perform a TSH test to measure your thyroid function. Good luck, I hope you stay warm.
