Overview Pelvic pain of sudden onset. Of women of reproductive age it is a ectopic pregnancy until proven otherwise. Refer immediately to gynaecology all patients with a pelvic mass, abnormal cervix, or persistent bleeding
| Definition Chronic pelvic pain (CPP): refers to pain of at least six months' duration that occurs below the umbilicus and is severe enough to cause functional disability or require treatment. Acute pelvic pain: generally defined as pain in the lower abdomen or pelvis lasting less than three months. In women, it can pose a challenging clinical scenario in which history and physical examination findings are often nonspecific, and the clinical presentation of each condition can vary widely. |
Differential Diagnosis
Acute pelvic pain - Gyaenacological
Acute Pelvic Pain - Non-Gyaenacological
| Remember In a pregnant woman these differential will be different as the pain might be due to the obstetric complications |
| Side note In Adolescents don't forget transverse vaginal septum and imperforate hymen |
| Think In postmenopausal women who present with acute pelvice pain, ectopic pregngnacy and ovarian torsion is unlikely |
Chronic Pelvic Pain will be discussed elsewhere
