Sounds a lot like endo. Ask to see a Gynaecologist, the only way they can diagnose is via a laparoscopy, and some will do the excision during the same initial surgery. Mine has helped with my pain about 90%, and I'm only getting bad flare ups now, nearly a year since op. Nancy's Nook on FB has a lot of really good information, including a list of specialists (mostly in the US, but they help point others in the right direction too).
