But the bleeding in your cough is why the first medical visit is a must.  Consult a pulmonologist for proper treatment advice.

Shortness of breath, especially worsening at night, can be concerning.

I recommend you consult your pulmonologist for further assessment, as they can guide you through appropriate next steps and ensure your well-being.
