DRY NEEDLING

Dry needling can ease irritation around a nerve root mainly by targeting myofascial trigger points—tight, dysfunctional areas within muscle tissue. These spots tend to have poor circulation and a buildup of pain-related chemicals. By inserting a needle into the trigger point, the muscle is stimulated to release tension and return toward a more normal state.

 

One common response is a brief, involuntary contraction known as a local twitch response. This reaction is thought to disrupt abnormal activity within the muscle and reduce the concentration of sensitizing substances such as bradykinin and substance P. As the muscle relaxes, blood flow improves, bringing oxygen and nutrients into the area and helping restore a healthier chemical balance.

 

The needling process also promotes changes in local circulation. It can trigger the release of substances that widen blood vessels, increasing blood supply to previously restricted tissue. This supports the removal of irritants and improves the overall metabolic environment.

 

In addition to local effects, dry needling influences how the nervous system processes pain. It can reduce heightened sensitivity along nerve pathways and alter pain signaling, making the affected area feel less painful.

 

By decreasing muscle tightness and improving tissue health, dry needling reduces stress on nearby nerves. While it does not directly correct structural causes of nerve compression, it can relieve symptoms by addressing the muscular and neurological factors that contribute to pain.
