Question
A patient has been experiencing a persistent feeling of coldness in the back, thighs, and outer arms since the abortion in May 2011. Sometimes, other parts of the body also feel cold. Laboratory and examination results show no abnormalities. Both traditional Chinese medicine and orthopedics have prescribed herbal medicine to replenish kidney qi deficiency or heart and spleen deficiency, but the long-term use has not yielded good results, and now there is often a dry and bitter taste in the mouth. The patient wants to know what kind of disease they may have, how to treat it, and which medications to take.
