Pelvic pain is a symptom that can affect both women and men. The pain may indicate the existence of poorly understood conditions that likely represent abnormal psychoneuromuscular function. 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. On the other hand, pain that extends beyond a normal recovery period and lasts longer than 3–6 months constitutes chronic pain.[1]

Female[edit]

Most women, at some time in their lives, experience pelvic pain. As girls enter puberty, pelvic or abdominal pain becomes a frequent complaint.

According to the CDC, Chronic pelvic pain (CPP) accounted for approximately 9% of all visits to gynecologists in 2007.[2] In addition, CPP is the reason for 20—30% of all laparoscopies in adults.[citation needed]

Cause[edit]

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)
Gynecologic
  • Dysmenorrhea—pain during the menstrual period
  • Endometriosis—pain caused by uterine tissue that is outside the uterus. Endometriosis can be visually confirmed by laparoscopy in approximately 75% of adolescent girls with chronic pelvic pain that is resistant to treatment, and in approximately 50% of adolescent in girls with chronic pelvic pain that is not necessarily resistant to treatment.[3]
  • 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
Abdominal

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.[4]

Workup[edit]

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.[1]

Treatment[edit]

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.[5]

Male[edit]

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.[6] There are no standard diagnostic tests; diagnosis is by exclusion of other disease entities. Multimodal therapy is the most successful treatment option,[7] and includes α-blockers,[8] phytotherapy,[9][10] and protocols aimed at quieting the pelvic nerves through myofascial trigger point release with psychological re-training for anxiety control.[11][12] Antibiotics are not recommended.[13][14]

Differential diagnosis[edit]

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.[15]

Epidemiology[edit]

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%.[16]

Social Implications[edit]

In the pursuit of better outcomes for patients, numerous problems have been found in current procedures for the treatment of Chronic Pelvic Pain (CPP). These relate primarily with regard to the conceptual dichotomy between an ‘organic’ genesis of pain, where the presence of tissue damage is presumed, and a ‘psychogenic’ origin, where pain occurs despite a lack of damage to tissue.[17] CPP literature in medicine and psychiatry reflects a paradigm where unproblematically observable ‘organic’ processes are causally and sequentially explained, despite evidence in favour of a possible model which accounts for the “complex role played by meaning and consciousness” in the experience of pain.[18] While in the literature of causal mechanisms reference is made to ‘subjective’ aspects of pain, current models do not provide a means through which these aspects may be accessed or understood.[19] Without interpretive or ‘subjective’ approaches to the pain experienced by patients, medical understandings of CPP are fixed within ‘organic’ sequences of the “purely object” body conceptually separated from the patient.[20]

Despite the prevalence of this wider understanding of the biological genesis of pain, alternate diagnosis and treatments of CPP in multidisciplinary settings have shown high success rates for patients for whom ‘organic’ pathology has been unhelpful.[21]
