Be seen today
Arrange a prompt medical assessment if you have a persistent cough, fever, unexplained weight loss, worsening breathlessness, or blood in your mucus.
These symptoms have many possible causes and do not by themselves mean you have nocardiosis.
If you are being treated for pulmonary nocardiosis, seek same-day advice for worsening fever, increasing breathlessness, repeated vomiting that prevents you taking antibiotics, a spreading rash, or other significant treatment side effects.

Routine follow-up is still important when you feel better.
Blood tests and repeat imaging are used to check treatment response; they are not signs that the condition has necessarily worsened.
Every sign above is quoted from the sofidex article on Pulmonary nocardiosis. If you are not sure, err upward — it is always reasonable to be checked.
