A Case Report of the Ongoing Management and Comorbidities of Loin Pain Hematuria Syndrome with an Unusual Presentation.

Loin pain hematuria syndrome (LPHS) is a rare chronic pain disorder that is poorly understood. LPHS presents as unilateral or bilateral flank pain with hematuria of unknown cause. The lack of knowledge surrounding pathogenesis and effective treatment has resulted in missed diagnoses as well as narcotic addiction in some patients. In this case, we describe the presentation and management of a 30-year-old female with a history of anxiety, depression, chronic pelvic bleeding, and pain recently diagnosed with LPHS after a total hysterectomy. She presented with ongoing pelvic pain symptoms with recent tachycardia, recurrent urinary tract infections, and nephrolithiasis. Loin pain hematuria presents as a particularly rare and difficult diagnosis to manage with multiple, sometimes unpredictable, comorbidities. This case serves as an example of a unique presentation with additional uncommon symptoms.
