What Conditions Can Make Me Feel Feverish and Sluggish But Not Have A Fever?

Even without measuring a fever, you can still feel chills, feverish or sluggish from some sort of infection. Your body temperature measurement can vary depending on how and where you measure your temperature. So you may actually have a fever or are about to spike a fever if you feel chills or feverish. Beyond infection, there are many different diseases that may cause such symptoms like endocrine disorders such as hypothyroidism/hyperthyroidism, menopausal disorders, inflammatory or autoimmune diseases and fatigue. Typically these conditions present with other symptoms beyond feeling feverish, so you may want to consult a health care provider for further evaluation.
