I am 57 yrs old female, postmenapausal, hysterectomy at age 30 due to endometriosis, removing only my uterus and leaving both ovaries intact. For the past few months, I have had pain in my left side...in the area of my ovary. 4 days ago, I experienced the onset of numbness of my skin on my left side and the area enlarged and got more numb as the day went on. Could this be a cyst on my ovary that is growing and causing the numbness?
