Abstract
ABSTRACT
Because acupuncture has a long history of use, especially to relieve pain, both patients and therapists believe that it carries few risks as long as sterile needles are used. However, as shown by previous reports, acupuncture can cause various adverse effects such as hemorrhage, infection, and dizziness. An 81-year-old woman presented with swelling and severe pain in her right hand. The cause of the swelling was unclear although a septic tenosynovitis due to acupuncture was initially suspected. Hemorrhage in the carpal tunnel was found during surgery. Hemorrhage can increase the pressure in the carpal tunnel. Patients taking anticoagulant therapy are more likely to develop hemorrhage or hematoma as a result of acupuncture therapy.
