sounds like what everyone has said is normal. I have had two c/s in 2002 and 2004 (7 and 5 years ago)
After 5 years I still have numbness just above and just below my scar. It dosn't bother me anymore as its such a small area.
I have spoken to people who have complete feeling around their scar but it does take time. Take care and allow your body to heal. It will get better
