TRIGGER POINT INJECTIONS

Trigger point injection is a therapeutic procedure that involves multiple advances of a small filament needle and injection of a topical anesthetic such as lidocaine into the muscle of the body which produces pain and typically contains a trigger point. When no injectable solution is used, this procedure is referred to as dry needling. Most patients will not even feel the needle penetrate the skin, but once it advances into the muscle, the discomfort can vary from patient to patient. Usually a healthy muscle feels very little discomfort upon insertion of the needle; however, if the muscle is sensitive and shortened or contains active trigger points, the subject may feel a sensation much like a muscle cramp, often referred to as a “twitch response.”

The patient may only feel the cramping sensation locally or they may feel a referral of pain or similar symptoms for which they are seeking treatment. A reproduction of their pain can be a helpful diagnostic indicator of the cause of the symptoms. Patients soon learn to recognize and even welcome this sensation, as it results in deactivation of the trigger point, reducing pain and restoring normal length and function of the involved muscle. Typically, positive results are apparent within 2-4 treatment sessions but can vary depending on the cause and duration of the symptoms, overall health of the patient, and experience level of the practitioner.

Trigger point injection/Dry needling is an effective treatment for acute and chronic pain, rehabilitation from injury, and even pain and injury prevention, with very few side effects. This technique is unequaled in finding and eliminating neuromuscular dysfunction that leads to pain and functional deficits.
