I have suspected endometriosis and it's always been on a flare up basis.. I say suspected as I haven't had a laparoscopy yet to confirm it. Where symptoms went away (never for long) and have came back. However apart from my periods my symptoms have been practically non existent for about 6 months which is the longest I have ever felt symptom free. However in the past week or so I've noticed the same symptoms returning again. Would it be possible for it to subside for this length of time?
