How results build over a course of sessions
Acupuncture usually works gradually rather than in a single visit, because the response tends to build as points are stimulated over time. Many people are offered a short course of sessions and then reassessed.
How many sessions help varies by person and by condition, so the number is discussed at your first visit rather than fixed in advance. A common approach is to try a defined series, review the change in symptoms, and decide together whether to continue.
Progress is judged by how you feel between visits, such as less pain, better sleep, or easier movement, because those day-to-day changes are what matter most.
