I have some slight pain from time to time and it will itch. But I've also had 3 C/S and I didn't notice it until after my 3rd. 

itching, and pain? kind of sounds like a keloid. is it a raised scar? try 100% pure tea tree oil. it helped my scars sooo much. but yeah, mention it to your doctor for sure.

I haven't had a C-section either, but one of the four scars from the gallbladder removal still hurts at times...it's lower on my abdomin than the others/in about the same region. The other three sites are perfectly fine, but that one? Not my friend. So perhaps it's just the area?

I had a c-section with my first and I have had pain from it. The pain is usually sudden and very intenses, I feel a pop or tear and am almost doubled over in pain. Sometimes I have some spotting from it. It was really bad during my first pregnancy after my c-section. All my other childbirths were natural so I don't know about reopening the wound. My doctor said to remember that the c-section scar is actually three scars. The outer scar that we see that is on the surface. The scar that cut through the muscles and then the scar on the unterus itself. He said that as the skin and muscles stretches the scar tissue pulls and tears causing the pain. It has been 21 years since my c-section and I have had 4 other natural childbirths since then but I still get one of those sharp pains once in a while usually when I'm exercising or dancing or something that stretches and pulls the muscles in that area.

This is encouraging for me to read, because following my c-section 3 years ago I had quite a bit of incisional pain too. And all I kept seeing online at the time was from these Moms who said they were like 6wks post pardum and already feeling perfect and wearing bikini underwear. Not me! Anything that touched around my incision for at least 6 months was painful. I had a VBAC 6 months ago (woo!) and my son keeps somehow findng my old incision with his toes. That still hurts.

I've had 2 c-sections, and my scar was reopened for my second csection.  I will have a 3rd c-section with this child due in late February.  I didn't have much pain at all with the last pregnancy, but with this 3 one, with my scar being reopened, I've had a few major cramps and sharp pain during my first and second trimester.  It might be because my scar is weaker because it's been reopened and in addition, my body is changing and growing to make room for baby #3.  I haven't felt pain for 3 months now,  I think my scar is or has adjusted to equal growth of my uterus and baby.
