Mgt: If you are still producing sputum, please see your PCP for a sputum culture, screening for Strep and other bacterial causes. If there is a prolonged viral illness, inflammatory changes may occur in the airway, and the need for an anti inflammatory drug can be evaluated. A virtual appointment may be helpful to you and your PCP. Your medical record and chest Radiograph result may be uploaded.
