My son is eighteen years old and has a lot of earwax in his ears. It's only been a day since he took it out. Is this healthy?

Earwax is mostly the result of exuberant secretion of ear glands and will not affect health. Ear symptoms caused by cerumen embolism, especially dry and hard earwax, are often dropped with 5% baking soda solution, 3-4 times a day, 2-3 drops each time. After 3 days, the earwax will soften, and the doctor will take it out with special hooks or pliers, or rinse it with warm salt water.
