From an East Asian Medicine perspective, it simply works by regulating Qi and Blood to modulate various effects.

It becomes more complex when viewed from a Biomedical perspective:

Endorphin Release: Acupuncture may stimulate the release of endorphins, which are natural pain-relieving chemicals in the body. This can contribute to pain reduction and an overall sense of well-being.

Neurotransmitter Regulation: Acupuncture may influence the release and activity of neurotransmitters in the central nervous system. For example, it may affect serotonin and noradrenaline levels, which can have mood-regulating effects.

Gate Control Theory: According to the gate control theory of pain, acupuncture may stimulate certain nerve fibers that interfere with pain signals, essentially "closing the gate" to pain perception.

Modulation of Inflammation: Some studies suggest that acupuncture may have anti-inflammatory effects by modulating the release of cytokines and other immune system components.

Blood Flow and Microcirculation: Acupuncture may influence blood flow and microcirculation in the body. Improved circulation can contribute to tissue healing and recovery.

Connective Tissue Stimulation: Acupuncture needles may stimulate connective tissue, leading to local and systemic effects. This stimulation might influence the transmission of mechanical signals and cellular responses.

It can, but I aim to make it as painless as possible.

You will most likely feel sensations of pressure, heaviness, or a minor awareness of the point throughout your session. This is known as Dé Qì sensation and indicates qì at the point.

There may be sharp or burning sensations upon needle insertion. Pain is not my intention, and if it does occur please notify me and we can adjust the needle or take it out completely.

If you are nervous or scared of needles, we can utilize different non-insertive needle techniques and modalities that still encompass East Asian Medicine Principles.

I like to think of one acupuncture session as one dose of medicine. Each session builds upon each other. It is similar to physical therapy in that manner.

Every person is different and everyone will respond differently to acupuncture. It can take time for your body to get used to it, and the amount of sessions needed varies depending on your state or condition.
