I can hear the heartbeat in my right ear for a month. It's always banging and annoying. I don't know why, what medicine to take.

I had the same problem as the landlord for a while. I'm in my left ear, and there's always a sound in my ear, which sounds like a heartbeat. The final diagnosis was otitis media. The landlord should pay attention to protecting his ears, such as taking a shower and swimming, and dealing with it immediately. Don't let dirty water stay in his ears, because the water is full of bacteria (it will be much better to dry it with a cotton swab). The landlord should be in the same class as me and have sensitive ears. Nothing ordinary people say makes any difference. It is suggested that the landlord consult an authoritative doctor when necessary, and the doctor will judge your symptoms and give the best treatment plan.
