If you did not have : a Quick-Srep Test or throat culture that was positive for Group A Streptococcus before starting antibiotics, no one can know if "strep throat" was or is the cause of your symptoms. You'd have to stop antibiotics for a while to obtain a valid throat culture, but your doctor can order blood tests for antibodies to mononucleosis & strep & look for other causes of your protracted symptoms.
