Key points for Diagnosis:
(1) It is often seen in the young females at the age of 20 - 30.
(2) It is often induced by cold irritation or emotional excitement.
(3) In acute attack, the skin of the fingers is in pale color and then in purple color. The affection starts mostly from the tips of the fingers and progressively involves the whole fingers and even palm. After several minutes, the purple color becomes flushed and finally the skin color becomes normal. It can be accompanied simultaneously by cold sensation, numbness and picking pain, or burning sensation and other abnormal sensations.
(4) In those with frequent seizure and severe condition, the skin becomes thin or thickened, accompanied by deformed and fragile nail and atrophic finger pads, ulcer or gangrene in the fingertips.

In TCM, a disease or a symptom might be caused by one pathogenic factor, even two or three pathogenic factors. When diagnosing a disease or a symptom, TCM doctors must follow the principle of "Syndrome Dfferentiation", and then "Suit the Remedy to the Case". In order to gain a more definite and valuable diagnosis, it's important and necessary for the doctor to learn the detailed health information of the patient, including his/her disease duration, age, sex, height, weight, family history, urine, stool, diet, sleep, sweat, energy, mood (emotion), as well as the tongue conditions and the palm conditions, etc. If you would want our expert to create a TCM diagnosis, you're welcome to contact us.
