For 10 days, I have run a low grade fever, had what felt like sinus, runny noise, sneezing, no energy, very, very tired, have taken Clairitin, symptoms have not improved. Should I go to my internist? Symptoms not serious - just feel groggy like the flu, but no chills, no high fever - just not myself, age 70, white female, post menopausal, normally very active, cleaning house, cut and edge grass/lawn/ work out gym 3 times a week. Not me.
