C Section Scar

I had a C section a little over 9 months ago...... my little one loves to crawl on me so I let her but EVERY time she gets near my scar or on my scar I have terrible pain. It's numb around that area but I feel sharp pain when she puts a knee or foot or even a hand there (usually I let her pull up on me if I'm laying down)....... she got me pretty good today it hurt so bad I cried out in pain involuntarily. Is this normal ???? The scar itself looks perfect it's barely visible!
