Petite anecdote à corriger SVP. J'ai du faire quelques fautes merci de m'aider

Je te fais la suite :

To save time, I filled the medical record while the child sits on the dental chair and cries...

The boy's mother was impatient, so I started to panic, tremble. My mother still wasn't there and I was forced to do something. So I took the syringe to anesthetize the child. He started to scream and tries to bite my hand. In the end, his teeth falls down. However, there was blood everywhere and I did not feel good. Indeed, I fainted.
