Phoned 111 again at 9pm who made me wait 3 hours before deciding to send me to the out if hours GP at the hospital. There I saw the most helpful doctor I've ever seen. He had a book on his desk ready marked with a page on endo. After vomiting in front of him, he gave me a pain relief injection, and an anti sickness injection and has sent a report to my GP telling them to refer me to a gynecologist. Feel so relieved. I know there is still a long way to go but at least the journey has started.
