A young woman presented with multiple central hypersensitivity disorders, including fibromyalgia, headache, pelvic pain and several smooth muscle spasm disorders, including irritable bowel syndrome, irritable bladder and Raynaud’s phenomenon. She also had significant fatigue and sleep problems. Her case illustrates the importance and surprising frequency of atypical bipolar mood disorders in people with multiple central hypersensitivity pain disorders, especially with depression and anxiety resistant to antidepressant treatment.

Considering neurological mechanisms common to her overlapping disorders was very helpful in guiding treatment choices. This experience illustrates the value of serotonin receptor type 2 (5HT2) inhibition with atypical neuroleptics, of neural cation channel and glutamate inhibition with anticonvulsants, and the potential usefulness of antidepressants after establishing 5HT2 control to enhance downward inhibitory tracts.

Medications with combined usefulness for both bipolar mood and pain disorders were highly effective for her multiple hypersensitivity problems.
