Sudden, unexpected pelvic pain
Pelvic pain that comes on suddenly for the first time is called acute pelvic pain.
See your GP immediately if you have acute pelvic pain. They'll be able to investigate the cause and arrange any treatment you may need.
Common causes of acute pelvic pain
The most common causes of acute pelvic pain in women who aren't pregnant are:
- an ovarian cyst – a fluid-filled sac that develops on an ovary and causes pelvic pain when it bursts or becomes twisted
- acute pelvic inflammatory disease – a bacterial infection of the womb, fallopian tubes or ovaries, which often follows a chlamydia or gonorrhoea infection and needs immediate treatment with antibiotics
- appendicitis – a painful swelling of the appendix (a finger-like pouch connected to the large intestine) which usually causes pain on the lower right-hand side of your abdomen (tummy)
- peritonitis – inflammation of the peritoneum (the thin layer of tissue that lines the inside of the abdomen); it causes sudden abdominal pain that gradually becomes more severe and requires immediate medical treatment
- a urinary tract infection – you'll probably also have pain or a burning sensation when you urinate, and you may need to urinate more often
- constipation or bowel spasm – this may be brought on by changes in diet, medication, irritable bowel syndrome or, in rare cases, a bowel obstruction
Less common reasons for acute pelvic pain
Less common causes of acute pelvic pain include:
Long-term pelvic pain
If you've had pelvic pain for 6 months or more that either comes and goes or is continuous, it's known as chronic pelvic pain.
Chronic pelvic pain is more intense than ordinary period pain and lasts longer. It affects around 1 in 6 women.
See your GP if you have chronic pelvic pain. They'll investigate the cause and arrange any necessary treatment.
Common causes of chronic pelvic pain
The most common causes of chronic pelvic pain are:
- chronic pelvic inflammatory disease – a bacterial infection of the womb, fallopian tubes or ovaries, which often follows a chlamydia or gonorrhoea infection and needs immediate treatment with antibiotics
- irritable bowel syndrome – a common long-term condition of the digestive system that can cause stomach cramps, bloating, diarrhoea and constipation
Less common reasons for chronic pelvic pain
Less common causes of chronic pelvic pain include:
- constantly returning ovarian cysts – these are fluid or blood-filled sacs that develop on the ovaries
- a urinary tract infection that keeps coming back
- lower back pain
- prolapse of the womb – where the womb slips down from its normal position and usually causes a "dragging" pain
- adenomyosis – endometriosis that affects the muscle of the womb, causing painful, heavy periods
- fibroids – non-cancerous tumours that grow in or around the womb; fibroids can be painful if they twist or deteriorate, but uncomplicated fibroids aren't usually painful
- chronic interstitial cystitis – long-term inflammation of the bladder
- inflammatory bowel disease (IBD) – a term used to describe 2 chronic conditions, ulcerative colitis and Crohn's disease, which affect the gut
- a hernia – where an internal part of the body pushes through a weakness in the surrounding muscle or tissue wall
- trapped or damaged nerves in the pelvic area – these may cause sharp, stabbing or aching pain in a specific area, which often gets worse with certain movements
