Having Fever Frequently From 2 Months And Tiredness Increases In The Evening. All Tests Reported Normal. Reason?

Having fever on and off for last 2 months. (only in the evenings after 03.00 pm). slight temp of 100 (not more than 100). Red dots cluster appear on the legs with slight itching . And i feel overly tired. Especially in the evenings, energy level is totally low and weekends I tend to sleep the whole day because of tiredness. All the tests are normal and doctors are at a loss to know why this happens.

General & Family Physician,  's  Response
Hi and thanks for the query,
Fever with unknown cause could be fever of unknown origin (FUO). Before making this diagnosis, all possible diagnostic tests have to be done to rule out common viral, bacterial, tumoral, inflammatory and autoimmune causes of fever. This evaluation in an ideal situation should be done by a neurologist. Long term fevers should always lead to exclusion of Tuberculosis, pulmonary or extra pulmonary, sarcoidosis, connective tissue diseases and vasculitis. A complete blood count might be very helpful in orienting towards an anemia or raised white blood cells counts. These could be gateways to suspect hematologic malignancies.
I suggest you book and appointment with an internist for a proper assessment.
Thanks and best regards,
Luchuo, MD.
