Christy, i know how frustrating it is being in pain and just looking for an answer. i was the same when i was 13 all the way thru til 17. i was palmed off from one specialist to another, eventually they decided i had a lesion on my cervix which then led to thoughts of endometriosis and so the loooooong road of operations and pain killers began, only ending when i fell pregnant.
Have you thought that it could also be Irritable Bowel Syndrome, gross i know, but i have it too which made the endo harder to diagnose because they kinda work together in a pain force to be reckoned with. After i had my last endo operation i was still getting bad bad pain that was similar to endo but just a bit different, when i went back to the specialist who did the op he said there was absolutley no endo left, it had all been cut and burnt out and a dye had been run through my tubes and there were no blockages, he said that the cramping and stuff from IBS can present like endo too. i just happened to have both and sometimes couldnt tell the diff.
Sorry, i know thats probably TMI and long winded but hope it helps
Thanks for your tips on feeding
