Acupressure is often done by an acupuncturist. Depending on what points they need to access, you may sit or lie on a massage table during the session. You can also do acupressure on yourself. It is best to learn proper technique from an acupuncturist. In general, though, you apply pressure to a specific point using a thumb, finger, or knuckle. You can also use the tip of a pen. The pressure should be gentle but firm. The pressure point is primarily used to treat nausea and vomiting.Place your thumb at the center of where the hand meets the wrist. Move your thumb two finger-widths toward the elbow. The point is between two large tendons, which you should be able to feel as you apply pressure.
