Most often, people get acupuncture for pain: shoulder, neck, and back pain, headaches, and migraines. Next are people with insomnia. The last big one is women who are either pregnant or going through menopause and need relief from symptoms. A very common question and the biggest misconception about acupuncture. I understand that most people are afraid of needles. However, acupuncture needles are about the size of a strand of your hair. Acupuncture feels like a faint pinch.
