Every operation has risks and possible complications. Your question is too broad. It depends on how old you are and what plastic surgery you have done. The risks are different. Every coin has its two sides. The key is to find a regular plastic surgeon, understand its risks, and then decide whether to do it yourself. It's done. It'll look good. The probability of not doing well is 3%-5%. As for what it feels like to do badly, because the operation is different. It's a little bit like double eyelid surgery's after a while. It's swollen and fake, and the rhinoplasty prosthesis is slightly crooked. The doctor will talk to you before the operation and then sign it.
