A hard object inside the ear is mostly considered to be cerumen embolism, also known as earwax. The cerumen glands in the ear canal secrete a lot of fatty acids, which mix with the shed necrotic epithelial tissue and accumulate, gradually forming a larger cerumen, which is normal and physiological. Most of the cerumen will be discharged by itself, but a few of them are difficult to be discharged by themselves and form hard lumps that block the ear canal. If this happens, don’t worry, you can first use 3% sodium bicarbonate ear drops to soften the cerumen, 3-4 times a day, 3-4 drops each time, and then go to the ENT department of the hospital after 3 days, and the doctor will take it out according to the situation.
