                        My mother was plagued with this years.  She finally heard about a doctor at Massachusetts General Hospital.  She went there to a Doctor Sweet  and he performed an outpatient surgery that was successful.  This was about 25 years ago. She passed away 3 years ago and was 86 and it never returned.
