How long is it normal to feel recipient area numb?

Generally it goes away within a month or two, but sometimes it lasts for several months or even longer, there doesn't seem to be a pattern as to who does or doesn't have this issue.

Numbness is because trauma of the skin and may be observed untill first regrowing hair comes out from scalp skin . That complaint would go  away in a long time up to 3-6 months.
