Very confused . today doctors said i have pleuritis instead ? how can they say that based off just symptoms ? is it fatal ? gave me no treatment .

Do you have:: Chest pain that worsens when you breathe, cough or sneeze, Shortness of breath, cough and fever ? then that's enough to make the diagnosis but to know what caused the Pleurisy if you don't have a viral infection more investigation is needed. Treatment usually is pain control and treating the underlying cause. common causes: viral and bacterial infection, You might have a virus infection
