C section mamas

I'm 7mpp and yesterday I woke up with a red, semi swollen bump just above my scar(all the way to the left side). The best way I can describe it is a weird shape, quarter size bug bite. It only hurt to touch and was a little itchy. It went down threw out the day but then this morning when I woke up I had a red spot(not too swollen but hurts) right below where the bump was but on my scar. The bump from the day before is gone. My baby has been clingy and climbing on me so my husband thinks it's irration. Has anyone had this? I have an appointment next week and don't really want to go in twice if it's nothing. Thank you in advance!
