Actually when I can get any phlegm out it’s like pellets sized like half-a-pea to twice-a-pea. Specialists so far have passed me to the next. Pulmonary, ENT, GI. Next is allergy/immunology. Maybe? Hopefully? If so I’ll share. My research does lead me to histamine intolerance or MCAS, both of which are relatively recent recognitions and kinda like fibromyalgia meaning not fully recognized by mainstream medicine. As if we’re all quacks!
