Hi, I don't think its really anything for you to be overly worried about.
Just try to keep the area clean and don't wear anything tight until you
get approval from your doctor. I was told the numb feeling was from
nerve endings at the skin that was cut and it takes a while to heal. I
have been cut on twice and know its no walk in the park. I went back
to work 4 weeks as well, as a heavy press operator and that was too soon. Just take it easy girl, and if you think you have a problem that
needs checked, don't hesitate. Its your health, you know better than
any one else.

Good luck
