[|AI|]  Hi dear, I understand your concern, it seems she has fever with unknown cause. With such presentation in my clinic, we try to differentiate next statements:- intestinal infection, parasites (stool culture, stool for cyst, ova);-respiratory infections(thyroiditis, sinusitis-consulting of ENT doctor+nose, throat culture);-thyroid function (exclude hyperthyroidism-TTH,T3,T4);-autoimmune diseases (circulating antibodies, immunogramm);-UTI(urinalysis). Treatment depends on from cause, then we can receive results. Hope it helps to confirm diagnosis and prescribe correct treatment. You can discuss it with your treating doctor.
