What happens to the levels of pain chemicals in the body after dry needling?

After dry needling, the levels of pain chemicals in the body are reduced. This reduction in pain chemicals is associated with the physiological response that occurs when needles are inserted into trigger points or taut muscle bands. The mechanical stimulation of the muscle tissue leads to a local inflammatory response, which can help clear out biochemical irritants that contribute to pain sensation.

Furthermore, dry needling facilitates the release of endorphins and other neuropeptides that help modulate pain perception. The reduction in pain chemicals, such as substance P and other inflammatory mediators, can contribute to decreased muscle tension and improved mobility, thereby alleviating pain in the affected area. This therapeutic effect is part of what makes dry needling a valuable intervention for managing musculoskeletal pain.

In contrast, the other options do not accurately reflect the physiological changes that occur after dry needling. The increase in pain chemicals would contradict the goal of treatment, and stating that they remain the same or fluctuate does not capture the healing process initiated by dry needling techniques.
