I have gone through your query and understood the concern. Adenomyotic tissue can be seen anywhere and this tissue can show similar signs as the endometrium of the uterus
. The fact that your umbilicus
bleeds along with your normal menstrual cycles is making me think of a possible adenomyotic deposit there. In view of your intra-operative complications, this patch may have been ignored at the time. Please discuss with your consultant regarding this possibility. A sonogram or an MRI
of the abdomen should help detect the cause of the cyclical backache
. Hormones and styptics may be needed to control the bleeding. Hope you find this information helpful. Wish you good health.
