I doubt that it has a physical origin, but that is only a guess. What is ironic about it is that the treating physicians probably don't have a clue, but won't make that as a statement. So, a syndrome is born--pain and orgasms, with a trigger point in the pelvis. Therefore, desensitize that with massage. All of this is my interpretation. It is akin to a surgeon not knowing what is causing belly pain, but recommending an exploration "to look and see" the cause, rather than saying "I don't know. Let's wait and see." In this case, as surgeon points out something needs to be done. BTW, around here there is no longer abdominal pain, but abdominalgia. Does that make the patient feel like something is really wrong? Does the doctor feel smarter with such language? Is the reimbursement better?
I was told that the husband has no complaint, but the patient has lost control of her own response, and does climax at inappropriate times, such as during a rectal exam done by her physician. So there is a touchy subject here, expecially in the hands of males, who can easily be accused of being MCP's. Do remember the saying about dyspareunia?
I doubt it, just like priapism is a painful condition and not enjoyable.
