The University of North Carolina Department of Obstetrics & Gynecology reports that only about 2 to 3 percent of people who undergo a hysterectomy develop scar tissue. When this scar tissue develops during the healing process, it may cause the patient to experience additional pain in one or both of the ovaries.
The UNC Department of Obstetrics & Gynecology explains that this scarring may occur on one or both ovaries. Furthermore, the pain may recur in monthly cycles very much like a menstrual cycle, and the scarring may cause pain during sexual intercourse. The UNC Department of Obstetrics & Gynecology also explains that the scar tissue may not occur on the ovaries but at the very top of the end of the vagina where physicians place sutures during the surgery. When this happens, the patient may experience a neuropathic pain, which results from nerve endings sending out false pain signals.
The UNC Department of Obstetrics & Gynecology recommends finding out the source of the pain to make sure it does not come from the ovaries to avoid unnecessary removal. Instead, it advises using techniques to quiet the abnormal nerve signals, such as placing local anesthetics high in the vagina, injections, medications to decrease abnormal pain signals and surgical revision of the top end of the vagina.
