What happened to you?
I showed my finger and I said, "the car's..." (lost of words).
Then, the second Q: Was it slammed by car's door?
No! Scalded by the car's cigarette lighter's point.
Oh no! Hold on...
Doctor's advice is to put the 'burnt' finger on running water once it got burnt (I did that once I reached clinic), and do not apply chemicals such as toothpaste, soy sauce, etc. to release the pain (it wouldn't help).
Then, doctor put my 'burnt' finger on the cream to release pain. I felt a bit relieved after that, and I took medicine (painkiller), immediately.
