What Are The Chances Of Re Occurrence Of Endometriosis After Hysterectomy?

I had a hysterectomy back in 2002 and at that time had severe endometriosis. I still have one ovary and am wondering if it's possible that I could have a re-occurrence of endometriosis this many years after. I'm experiencing lower abdominal pain, slight nausea comparable to being car sick, fatigue, loss of appetite and have also noticed that my left breast is very very tender to the touch. Help
