I'm in my 5th week of recovery after my 3rd C-Section. I was showering last night and discovered the lump/knot on the left hand edge of my incision. It's not painful, but did freak me out. I go to the doctor in a week and as long as it doesn't look infected or becomes painful I will wait until my visit to talk to my doctor. If it hurts or is painful I would get is checked out.
