Hi and thanks for the query,
The symptoms described are compatible with a viral infection. Treatment of viral infections is generally symptomatic, with simple analgesics and passages clearing agents. Fatigue
could persist after a viral infection in morning doses of vitamin C
might be sufficient. However, intensification and persistence of symptoms might require other tests like complete blood counts and a detailed repeat physical examination to exclude a bacterial infection. I suggest if symptoms persist or aggravate to consult your family physician for reevaluation and appropriate management.
Thanks and best regards,
