Q. Do acupuncturists sterilize the needles before use (or) use fresh needle for new patient? My mom has just started taking acupuncture treatment for her severe constipation. She says that they prick her skin with needles. Some 7 or 8 needles are pierced in her skin. I want to know what may happen if the needle is not placed well? Do acupuncturists sterilize the needles before use (or) use fresh needle for new patient?

A. Only experienced and authorized Chinese medical practitioners treat the patients. Improper use of needles may lead to infections and therefore, need to be handled with care and caution. It can lead to fainting in some patients as well. Minor Bruising is possible. Acupuncturists use disposable needles these days which are pre sterilized to avoid the spread of hepatitis and HIV.
