Oh, there's lots of symptoms, big & small, from both trad. chinese medicine and western naturopathic medicine perspectives. You could consult with such practitioners and/or do some reading. Some common symptoms are feeling tense and cranky often; aches & pains that move around from one part of the body to the other; constipation; and so on. Much interesting info on www.sensiblehealth.com (Julia Chang's site) on the topic.
