12 weeks post c-section and am so sore!

Vanessa
After my c-section I healed up quickly and was only sore for a week or two. I was released to work with no restrictions at my 6 week check up. (I am a preschool teacher. I have the 2 year old class) everything has been going smoothly until this week. I am 12 weeks pp and my incision area is so sore and I get a few sharp pains. I havnt changed anything in my daily routine. Has anyone had this before? Could it just be my nerves waking back up? I'm not as numb as I use to be.
