So I was looking up endometriosis treatment from the point of view of the specialist and what their guidelines are / process to follow and I came across some brilliant info on the NICE website (National Institute for Health and Care Excellence).
Google "National Institute for Health and Care Excellence" - then select the pathways tab and search "endometriosis" a list of 6 items comes up - or select "endometriosis" from the alphabetical list.- I chose "Diagnosing and managing endometriosis". It's actually really useful to see the paths specialists need to consider and all the different diagnosis and management options there are available.
