Sorry to hear about all that you have been through and that you don't feel that people listen. I think they do, but a lot of the people on this board are going through the same thing that you are going through.
4 weeks over with a 10lb baby - ouch! I wonder if that maybe started some small internal bleeds that maybe started the adhesions or?? Did they see the adhesions when you had your c-sections? If not, the c-sections are probably to blame, that is certainly what started mine....
Here's hoping we all find pain-free days (or hours, or minutes....)
