Neuroacupuncture, also known as scalp acupuncture, may be the most effective treatment for pain. I just treated two patients: one with stomach pain from cancer, the other with angina. The effect was immediate, pain gone within seconds like turning off a switch. Neuroacupuncture is a modality that integrates traditional acupuncture with neuroscience. I use it for post stroke and brain surgery therapy and have just started to use it to treat visceral pain. It's been amazing!
