Endometriosis

Has anyone else here had endometriosis? I am beginng to think that I may have had this for a long time. I have complained about heavy periods and pain for 2 years to my FNP, she always told me I was just having perry menopause and my thyroid, well for 6 months before this Addisons thing came on I was having clotting and I now found out Addisons can be cause by hemorage, now for my sciatic nerve pain down my leg I was told that inflamtion of the pelvic area in endometriosis can cause that nerve problem, i also get like vibration feelings in vaginal area and legs to.  So they are telling me now I can have a hysterectomy done on the 5th, is this a smart choice? Will the leg pain go away? Anyone ever been like this before? CONFUSED! Thanks........
