Trigger Point Injection
Trigger point injection can help relieve tender muscle areas that are painful to the touch.
The injection is made using a small amount of local anesthetic (numbing medication) and/or a steroid (anti-inflammatory) into the area of pain.
The local anesthetic will numb the area, relieve the pain and decrease the muscle spasm, while the steroid will decrease inflammation.
