No it usually just happens randomly. I do apprecate your advice. I will talk to my surgeon.
Does it coincide with your period? I have seen endometriosis seed trocar site. This would result in the endometrioma cycling just like the lining of the uterus. I have also seen this in incisions for c-sectionsand even one from an inguinal hernia repair. See your surgeon again. He may need to consider excising the area.
I dont notice it feeling hot or really looking red. Just slightly pink from the scar. When its not swelled up the scar isent really noticeable and it doesnt itch or stay swelled up for very long.
Does it ever look red or feel hot to the touch? You could be developing mild infections.
