Pelvic pain is a symptom that can affect both women and men. The pelvic pain that persists for a period of 3 months or more to be considered chronic while less than this duration is considered acute. The pain may indicate the existence of poorly-understood conditions that likely represent abnormal psychoneuromuscular function. Differentiating between acute and chronic pain is important in understanding chronic pelvic pain syndromes. Acute pain is most common, often experienced by patients after surgery or other soft tissue traumas. It tends to be immediate, severe and short lived however, pain that extends beyond a normal recovery period and lasts longer than 3–6 months constitutes chronic pain.
Most women, at some time in their lives, experience pelvic pain. As girls enter puberty, pelvic or abdominal pain becomes a frequent complaint.
Chronic pelvic pain (CPP) accounts for 10% of all visits to gynecologists. In addition, CPP is the reason for 20—30% of all laparoscopies in adults.
Many different conditions can cause pelvic pain including:
- exaggerated bladder, bowel, or uterine pain sensitivity (also known as visceral pain)
- pelvic girdle pain (SPD or DSP)
- Dysmenorrhea—pain during the menstrual period
- Endometriosis—pain caused by uterine tissue that is outside the uterus
- Müllerian abnormalities
- Pelvic inflammatory disease—pain caused by damage from infections
- Ovarian cysts—the ovary produces a large, painful cyst, which may rupture
- Ovarian torsion—the ovary is twisted in a way that interferes with its blood supply
- Ectopic pregnancy—a pregnancy implanted outside the uterus
- Loin pain hematuria syndrome
- Proctitis—infection or inflammation of the anus or rectum
- Colitis—infection or inflammation of the colon
- Appendicitis—infection or inflammation of the bowel
Internal hernias are difficult to identify in women, and misdiagnosis with endometriosis or idiopathic chronic pelvic pain is very common. One cause of misdiagnosis that when the woman lies down flat on an examination table, all of the medical signs of the hernia disappear. The hernia can typically only be detected when symptoms are present, so diagnosis requires positioning the woman's body in a way that provokes symptoms.
The diagnostic workup begins with a careful history and examination, followed by a pregnancy test. Some women may also need bloodwork or additional imaging studies, and a handful may also benefit from having surgical evaluation.
The absence of visible pathology in chronic pain syndromes should not form the basis for either seeking psychological explanations or questioning the reality of the patient’s pain. Instead it is essential to approach the complexity of chronic pain from a psychophysiological perspective which recognises the importance of the mind-body interaction. Some of the mechanisms by which the limbic system impacts on pain, and in particular myofascial pain, have been clarified by research findings in neurology and psychophysiology.
Many women will benefit from a consultation with a physical therapist, a trial of anti-inflammatory medications, hormonal therapy, or even neurological agents.
A hysterectomy is sometimes performed.
MaleMain article: Chronic prostatitis/chronic pelvic pain syndrome
Chronic pelvic pain in men is referred to as Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) and is also known as chronic nonbacterial prostatitis. Men in this category have no known infection, but do have extensive pelvic pain lasting more than 3 months. There are no standard diagnostic tests; diagnosis is by exclusion of other disease entities. Multimodal therapy is the most successful treatment option, and includes α-blockers, phytotherapy, and protocols aimed at quieting the pelvic nerves through myofascial trigger point release with psychological re-training for anxiety control. Antibiotics are not recommended.
In men, chronic pelvic pain (category IIIB) is often misdiagnosed as chronic bacterial prostatitis and needlessly treated with antibiotics exposing the patient to inappropriate antibiotic use and unnecessarily to adverse effects with little if any benefit in most cases. Within a Bulgarian study, where by definition all patients had negative microbiological results, a 65% adverse drug reaction rate was found for patients treated with ciprofloxacin in comparison to a 9% rate for the placebo patients. This was combined with a higher cure rate (69% v 53%) found within the placebo group.
Chronic pelvic pain is a common condition with rate of dysmenorrhoea between 16.8—81%, dyspareunia between 8—21.8%, and noncyclical pain between 2.1—24%.
