Has anyone ever had a hematoma after nose surgery?!

It was a reoperation..
 Today, on the 7th day, I went to remove the stitches and remove the splint, and the doctor told me that it looked like it was filled with blood, so he took it out with an injection.. I also received an antibiotic injection and was prescribed medication for 7 days..
 He said it was better to wear a splint, so I splinted it again and went
 to the hospital 3 days later. I decided to visit the hospital...
 
I searched on the internet, but I didn't know it was this serious.
 The first surgery was a failure, so I decided to have a second surgery, but
 it's so gloomy and I'm so worried that I can't do anything..
  
I'd like to ask someone who knows about the phenomenon of infertility to respond.
 
1. The phenomenon of infertility. If you have it even once, even if you feel fine now, is there a high chance of inflammation or contracture later on?
 2. What choice should I make
 
if the contraception occurs at the next visit
 ? If I have to have surgery again  , there will be swelling in the nose after
 the silicone removal surgery, right
 ...? 3. Please let me know what I should not do when I am a defendant.
 3. For those of you who have experienced the phenomenon of being
 a defendant , please tell me what your current situation is...
