Under incision pain?

St

Hi ladies!

Went to OB on Friday for him to check on c-section incision and all looked great. Last night in the shower I noticed there is an area under the middle of my incision that is slightly painful and pink. Is this just the internal stitches healing? No pus or fever, and it’s not warm...it’s just strange that it popped up almost 3 weeks post surgery. Anyone experience the same? Will be calling OB in the morning just wanted to know if anyone had experienced something similar.
