Numbness of the hand after acupuncture may be caused by too much stimulation during needling, or it may be caused by improper posture of the arm during needling operation.
1. When performing acupuncture operations, many acupuncture points are located close to the corresponding peripheral nerves, if the needles used in acupuncture are too thick, or the amplitude of the acupuncture operation is too large, it is easy to stimulate the surrounding nerves, resulting in peripheral nerve damage, numbness, burning pain and other symptoms.
2. When the acupuncture operation is performed, the needle is left for a long time, and if the arm is kept in an inappropriate posture, or under pressure, it may lead to local nerve compression, and then a transient numbness of the hand occurs.
Acupuncture operation should be carried out by a professional physician, if the symptoms of acupuncture hand numbness, should be timely to the hospital to avoid delay, resulting in adverse consequences.
