Trigger Point Injection

Trigger points are an area of muscle injury that is in continual spasm. This causes localized pain as well as referred pain. Once a trigger point is identified, we can inject it under ultrasound guidance and achieve quick relief. The area is sterilely prepped and confirmed with palpation and ultrasound. A small needle is gently advanced into the focal area of spasm and gently injected with local anesthetic and steroid, thereby breaking up the spasm allowing blood flow and healing. Patients usually feel very good the first day due to the local anesthetic. They often feel a bit sore on day two from the mild trauma of the injection. After this blood flow can reach the injured area and healing commences. The procedure is low risk and well tolerated. It requires no sedation and can be done in the office.
