A description of a patient with CHS https://ecosoberhouse.com/ in Australia revealed that her CHS symptoms exacerbated her anxiety disorder, and she presented to the ED with anxiety plus vomiting 127.

A thin layer of topical capsaicin cream was applied to the abdominal region, chest, or back. Only one CHS patient returned to the ED within 3 days after receiving topical capsaicin; capsaicin was administered again, and the patient reported rapid relief and was discharged without further treatment 96. In a study of the treatment of neuropathic pain with topical capsaicin, the most common adverse effect was a burning sensation upon application, localized erythema, and nonproductive cough 106.
Clinical Trials
