Hi and thanks fr the query, At times even viral infections could produce very dramatic clinical signs and symptoms as such. But when symptoms become persistent, a keen and careful reevaluation is needed. is an absolute necessity in this case to carryout a chest X ray. It is very possible that this should be a bacterial pneumonia, necessitating an invasive treatment with antibiotics. Difficulties in breathing deserve to be investigate for complications such as pleural effusion (fluid in lungs). Other causes of respiratory distress mus also be borne in mind like asthma and heart disease. A clinical reevaluation, a complete blood count for white blood cell levels are a chest x ray are sufficient initial evaluation parameters that shall ascertain the diagnosis and severity of the condition, determining future management and follow up. I suggest you get another consultation. Kind regards, Bain LE, MD.
