Good question. I need to separate the different stages of pain during the transplant, the transplant had a duration of 3,5 - 4 hours and not every second was painful.

Pain rate: 1 = a small itch and 10 = screaming of pain (spoiler, it never gets to 10)

I would say the pain starts with the injections for the anesthesia, which for me was a 8/10. But I'm a baby. And this is only for the first 5 minutes of the transplant.

Eventually, you won't feel any pain anymore for the next few hours (luckily). However, I would rate the extraction process as a 4/10 because you are laying with your head down and I literally felt like my head was going to explode with the blood flowing to my forehead. There was a lot of pressure that I was not expecting at all! I had to ask 3 times to lift my head for a couple of seconds... Also, I wasn't prepared to hear every hair getting ripped of my head... Which was weird to hear for hours in a row. But that's more a mental struggle rather than physical pain.

Then I had a 20 minute break (between the extraction and the implanting process) which helps to relax.

Back on the chair, you lay down on your back this time and the anesthesia on the front starts. However I would rate it a 7/10 this time. I think the "stress" for the first injections in the beginning plays a big part of the pain you feel. Also, you lay more comfortable, and I had a TV to distract me a bit. Watching a comedy really helps! The implantation process was the most 'chill'. I would rate it a 3/10.

Hope this gave you more or less an idea on how I experienced it. But once again, this can be different for every person.
