Psychological Factors in the Management of Chronic Pelvic Pain Syndrome

Introduction

Chronic pelvic pain is a major public health concern, known to be as common as migraine (a severe throbbing headache) and asthma (swelling and narrowing of the airways). It is reported to be about 20 percent of gynecological consultations worldwide. However, comparatively less research has been performed on this condition, and healthcare professionals usually describe it as a challenge to manage, as multiple organs may be associated with pain. Individuals suffering from chronic pelvic pain syndrome often describe their experience as long, frustrating, and involves various predisposing factors. It also integrates with numerous biological, social, and psychological conditions, thus describing the complex, multifactorial nature of chronic pelvic pain. Therefore, it requires a multidisciplinary approach delivered by experienced healthcare professionals to manage chronic pelvic pain syndrome successfully.

What Is Chronic Pelvic Pain Syndrome?

Chronic pelvic pain (CPP) is a relatively common, chronic, persistent pain and disabling condition that occurs in the lower abdomen or within the pelvic structures. It can affect both men and women but is comparatively prevalent in women. The symptoms are perceived to originate from the pelvic organs and typically last for more than six months. It may be associated with comorbidities such as major depressive disorder, irritable bowel syndrome (a gastrointestinal disorder), and pelvic inflammatory syndrome (inflammation of the female reproductive system).

It is a form of centralized pain that develops in the area where the body has a low threshold for pain and is also considered a form of chronic regional pain syndrome. In centralized pain, a previous mild or moderate pain is experienced as severe, and even the touch sensations are interpreted as painful. It is estimated that one in seven women in the United States is affected with chronic pelvic pain, and about 50 percent of the cases remain undiagnosed. The prevalence of this condition is similar to asthma, migraine, and chronic back pain.

What Are the Symptoms of Chronic Pelvic Pain Syndrome?

Chronic pelvic pain is a frequent condition, especially during the reproductive years. Still, it can affect women at any time during their adult lives, originating even beyond menopause (the stopping of menstrual cycles). It can be the result of an underlying condition or be associated with other medical problems. CPP can be associated with psychological conditions such as anxiety and depression, affect work quality, and also cause a decrease in sexual satisfaction. Some of the common symptoms associated with chronic pelvic pain syndrome include:

• Persistent pain in the pelvic area and lower abdomen.

• Pain in the lower back, hips, and genital area.

• Pain during urination or bowel movement.

• Pain when sitting or standing for a long time.

• Pressure or heaviness in the pelvic region.

• Constipation or diarrhea.

• Bloating sensation.

• Pain during intercourse.

• Pain and discomfort during menstruation.

What Are the Psychological Factors of Chronic Pelvic Pain Syndrome?

Pain sensation requires perception and is an essential function of the brain. Pain has two dimensions: severity and the effect of distress it causes on the individual. Understanding the mechanisms of psychological factors is necessary as it may influence the experience of pain and its response patterns. CPP is associated with numerous primary causes or disturbances; hence, the physiopathology is complex. The association between chronic pain and mental disorders is extensively reported, and these conditions have a high prevalence in women.

The psychological factors commonly found in patients with chronic pelvic pain include anxiety, depression, child abuse, rape, and personality disorder. Studies have shown that the levels of anxiety and depression are significantly higher in patients with chronic pelvic pain. Around 57 percent of women have depressive symptoms, and more than 70 percent of patients have high levels of anxiety. Recent studies have also evaluated the relationship of psychological variables with sexual arousal and intercourse.

Catastrophizing (overestimating or exaggerating the likelihood of a negative outcome), pain-related fear, neuroticism (a level of emotional stability), and hypervigilance (extreme alertness or awareness) are the other psychological factors associated with chronic pelvic pain syndrome. The generalized anxiety disorder-7 (GAD-7) questionnaire and pain catastrophizing scale (PCS) are used to determine the levels of anxiety and catastrophizing in patients with CPP.

How Are the Psychological Factors of Chronic Pelvic Pain Syndrome Managed?

Chronic pelvic pain syndrome is a multifactorial condition and is poorly interpreted due to the complex interplay of the bones, muscles, and soft tissues comprising the pelvis. Therefore, it is best managed by a multidisciplinary healthcare team with appropriate skills and training to address various factors that are associated with chronic pelvic pain. The management of chronic pelvic pain syndrome includes:

• Initial Assessment and Investigations: It includes a thorough history, physical examination, and a review of previous tests and treatments. These examinations and investigations are holistic and may take considerable appointments to focus on all the components of the pelvis. For sexually active women, additional information may be required along with the physical examination.

• Analgesics: The underlying pathology of chronic pelvic pain is associated with an increase in inflammation or inflammatory mediators. Women with CPP frequently request analgesics; however, they must be taken consistently to maximum effectiveness while experiencing their limitations. Some non-steroidal anti-inflammatory drugs (NSAIDs) can inhibit ovulation and hence must be used for menstrual pain only. Cox-2 inhibitors are usually not recommended as adequate data is unavailable, whereas short-term opiates and occasional use of its mild formulations are preferred to long-term use of analgesics. Studies have also explored the use of tricyclic antidepressants, serotonin reuptake inhibitors, selective noradrenaline, and gabapentinoids in targeting chronic pelvic pain.

• Hormonal Therapies: The excessive use of menstrual products such as sanitary pads, tampons, and menstrual cups during dysmenorrhea (pain during menstruation) can irritate the perineum and pelvic floor muscles. Hormonal therapies are used as a key component in managing CPP, such as progesterone, Norethisterone, Levonorgestrel tablets, or combined oral contraceptive pills, as they improve hormonal balance and prevent pelvic pain.

• Psychological Approach: The psychological approach aims to focus on the fear of pain, catastrophizing, and behavioral avoidance in individuals experiencing CPP. Research has shown that cognitive behavioral therapy (CBT) and behavioral therapy are problem-focused approaches that benefit patients. Individuals with CPP have a high prevalence of psychological distress and functional impairment with mental conditions and existing physical health conditions that affect their daily activities. Therefore, identifying and assessing the comorbid conditions can help manage CPP.

• Physiotherapy: It is one of the essential components in managing chronic pain; however, there needs to be more evidence in the management of CPP. However, it may be recommended to some women and can be effective as it improves muscle function and has mental relaxation benefits.

• Lifestyle Modifications: Chronic pelvic pain syndrome is common in women who are juggling between work, studies, social activities, personal life, etc., which can lead to hormonal imbalance, stress, irregular menstruation, pelvic pain, and other conditions. Lifestyle modifications such as regular physical exercise, following specific dietary changes, consumption of a balanced diet, avoiding smoking and alcohol consumption, and adequate fluid intake are emphasized in women with chronic pelvic pain syndrome.

Conclusion

Chronic pelvic pain syndrome is a common health concern, especially in women, and can cause an economic burden on the healthcare system worldwide. Though the symptoms can be relatively managed, their recurrence can be debilitating and frustrating to many patients and healthcare professionals. Anxiety, depression, fear of pain, and catastrophizing are some of the psychological factors associated with chronic pelvic pain syndrome. Adequate clinical studies and advances in medical technology are necessary to understand the physiopathological and psychological factors of chronic pelvic pain syndrome.
