So, if you're a doctor, how can you recognize that you're having a feeling? Some tips from Dr. Zinn:Most emotions have physical counterparts. Anxiety may be associated with a tightness of the abdomen or excessive diaphoresis; anger may be manifested by a generalized muscle tightness or a clenching of the jaw; sexual arousal may be noted by a tingling of the loins or piloerection; and sadness may be felt by conjunctival injection or heaviness of the chest.
