5 weeks post-op, Feeling the numb scalp after FUE, is that normal?

When I get frightened, my skin and hairs will stand and now my scalp. Though it’s still numb, I can feel the skin of the scalp is standing when I got frightened and I can feel the transplanted hair as if they’re raising and the scalp feels more tight. Also my scalp still smell and I wonder if it’s the liquid used during my transplant 5 weeks ago.
