Dry needling is an alternative pain relief technique that physical therapists may administer for leg symptoms such as hamstring or calf tightness. It involves the insertion of a small, solid filament into a stressed muscle’s site of spasm and pain, also known as a trigger point. By doing so, the muscle relaxes and blood flow increases into the area, alleviating pain and improving motion.
Trigger points are often the result of an injury to a different part of the body, because other muscles overcompensate for imbalances and weakness in the injured area. Because of this overcompensation, muscle spasm occurs, causing discomfort and pain in the muscle.
Once dry needling resets the tone of muscle, your physical therapist works on correcting strength and mobility deficits in the muscle, which allows healing and prevents injury.
