Does any of this apply?
Book an appointment
Arrange a routine medical appointment if pelvic, genital or rectal pain persists, keeps returning or interferes with sitting, sleep, sex, urination or bowel movements.
Assessment is also appropriate if you have unexplained numbness or symptoms that started after pelvic surgery, childbirth or an injury.
The article also says
Seek earlier review if symptoms are rapidly worsening, you develop increasing numbness, or treatment causes fever, swelling, discharge or severe new pain.
Every sign above is quoted from the sofidex article on Pudendal neuralgia. If you are not sure, err upward — it is always reasonable to be checked.
