Causes of chronic pelvic pain

Chronic pelvic pain (CPP) is a common and debilitating condition, and yet remarkably little is known about what causes the pain. In this chapter we present a model of CPP which emphasizes the multifactorial nature of the problem. A range of physical causes are discussed, including endometriosis, pelvic inflammatory disease (PID), adhesions, irritable bowel syndrome, interstitial cystitis, musculo-skeletal factors and nerve-related pain. The role of the nervous system in the genesis and moderation of pain is explored. The importance of psychological factors is discussed, both as a primary cause of pain and as a factor which affects the pain experience. As with other chronic syndromes, the biopsychosocial model offers a way of integrating physical causes of pain with psychological and social factors
