I am concerned about ear pain when swimming.

Recently, while swimming, I suddenly experienced ear pain.

As I entered the water to start swimming, I felt a tearing pain.

I have never had my eardrum torn, so I'm not sure, but if the eardrum were to tear, it would feel like this kind of pain.

I'm fine right now, so I haven't gone to the hospital. Is that okay?

Since then, I have been free of pain even when swimming.

I asked others, and they said they've experienced that at least once, but is it okay just to leave it as it is?
