Carpal Tunnel Syndrome is usually caused by irritation of the median nerve. The irritation is usually in the wrist at the wrist crease, but I have found it an also be as much as an inch above or below that as well . The key is finding where the irritation is. Being an Electrical Engineer as well as an acupuncturist, I have developed an electro-acupuncture technique that works as good as cortisone but uses electricity instead of drugs. You also do not have the limitation of only 3 treatments. You can repeat treatments as long as necessary. You can cause problems if done improperly, however. Other acupuncturists don’t know how to do this treatment unless they were taught by me or figured it out themselves. Once the problem area is found (usually where there is quite a lot of pain when palpated but not always), the pain will diminish with each treatment. A typical case will usually take 4 treatments. The more severe the inflammation is, the more treatments it will take. And if the patient continues to aggravate it from some activity it will take longer as well of course.
