I crushed and killed the bee, and then immediately took off my clothes. Fortunately, the stinger remained, so I was able to quickly remove it. I then used my fingernail to squeeze out the poison and washed it with water, and thankfully, it didn't seem serious.
It might swell up tomorrow.
After that, when I touched it, it felt a little stiff and slightly irritated, so I thought I should put on some medicine. I went to a pharmacy, and they told me to put a Band-Aid on it. Is that really necessary? Maybe it's so common here that it doesn't even count as an injury.
Then, I got some medicine at a different pharmacy. I'll just observe it for now.
