I underwent a hair transplant procedure a few years ago and I can honestly say that there was some discomfort during the process. The anesthesia injections can sting a bit, but once they kick in, the pain is minimal. During the procedure, you may feel some pulling or tugging sensations, but it's bearable.
In terms of recovery, the first few days were a bit uncomfortable with some swelling and soreness, but with proper care and pain management medication, it was manageable. Overall, the discomfort was worth it for the results I achieved. Just be prepared for some discomfort during the procedure and a few days of recovery, but the end result is definitely worth it.
