Trigger point injection with bupivacaine
Trigger point injections will be performed within an hour of arrival in post anesthesia care unit, given that the patient has adequately woken up from general anesthesia. Injections will be performed by an anesthesiology provider using a standardized technique under strict aseptic conditions. The trigger point will be located between two fingers, and a 1-2cm sterile needle with a thickness of 25 or 26 gauge inserted at 30 degrees with respect to the skin. Negative aspiration will be confirmed before injecting the study solution. The needle will be withdrawn to the subcutaneous tissue and redirected superiorly, inferiorly, laterally and medially, injecting study solution at each location. Pressure will be applied to the area to ensure hemostasis, and the area dressed with gauze and tape as needed.
Trigger point injection with normal saline

Lidocaine skin wheal
"Patients in the control group will receive a small skin wheal of lidocaine. This will keep the patient blinded to the study group they are in since all patients will receive an injection.~However, this skin wheal is not considered a trigger point injection."
