What to do when coughing up phlegm and causing ear infections

First go to the hospital to see if you have oozing otitis media, if so, first draw out the fluid in the eardrum and drum up the eardrum. If you go home and eat some high-quality phospholipids, you'll be cured in a month or so. In the future, if you keep eating it for a while, it will probably not recur. Phospholipids can regulate endocrine secretion, and when the glandular ducts are open, it will not secrete into the eardrum. I wish you good health soon!
