One hand is hot and one hand is cold, Chinese medicine believes that it is caused by poor qi, meridian obstruction, one side of the limb blood running poorly or one side of the limb is cold and other reasons will lead to this symptom. The specific cause of the disease should be judged according to the actual situation of the patient, can not be identified by a symptom, the patient should go to the regular hospital diagnosis and treatment in a timely manner. Poor blood circulation in one side of the limb is mostly seen in post-stroke and bed-ridden patients with prolonged illness, whose unilateral limbs have been under pressure for too long, leading to blood stasis and poor blood circulation; it is also seen in qi stagnation, which is unfavorable to blood circulation and poor transmission of fluids, and is prone to cause blood stasis and other symptoms. If qi stagnation occurs in one arm, the blood in the arm runs unfavorably; hence the situation of one hand being hot and one hand being cold. A cold limb on one side may be due to prolonged exposure of both hands to different temperatures, such as one hand in the pocket and one hand blowing in the wind, which will result in different temperatures in the two hands, resulting in one hand being hot and one hand being cold. If you have any related symptoms, please consult a doctor and get a prescription from the relevant Chinese medicine practitioner for face-to-face consultation.
