Question about pain after hairtransplant. Is the pain permanent?

[Paso]

I've been doing some reasearch on hairtransplants. But I've read cases where people have pain near the donor area, or numbness of some sort. I've heard cases where there is pain in donor area 4 years after hair transplant. Is this permanent pain and numbness? Does it go away over time?

Do I have to take "pain killers" for life, or does the pain just go away overtime?

I'm in a great need for some answers please, and thank you.
