That sounds absolutely exhausting, and the frustration of dealing with this for 8 months is completely understandable. A persistent cough with phlegm can actually be a sign that fluid is building up in the lungs, which is something that needs to be taken seriously with HCM. The phlegm you're describing is worth paying close attention to. Here's what to watch for:

- White or pink-tinged mucus — pink can mean it contains traces of blood
- Frothy or bubbly mucus — this is a particular warning sign
- Cough that's worse when lying down
- Cough accompanied by shortness of breath

These can all be signs that the heart isn't pumping as efficiently as it should be, causing fluid to back up into the lungs. Three days off medication is not long enough to rule out a drug-related cause, but given how severe the symptoms are — especially vomiting from coughing — this really needs urgent medical attention rather than a wait-and-see approach.

Please don't wait on this. Contact your cardiologist or care team right away and describe exactly what's been happening, including the phlegm and vomiting. If symptoms feel urgent, seek emergency care.
