Hi Heather,
Yes, I am familiar with trigger point injections. This refers to injecting a mild solution (usually saline and marcaine) into a palpable band within a muscle. I've had lots of these over the years, trying to relieve a spine condition. If the practitioner does trigger point injections the official way (developed by the late Janet Travell), he/she should get a "jump" or "twitch" response during the injection. After injection, strecth is very important - to restore the muscle to proper resting length. As far as trigger point injections inside the mouth...maybe into the lateral pterygoid or masseteur muscles, I've never had these. My pysiatrist injects these from outside the face, but she is sending me to a tmj dentist who is very comfortable doing them intraorally.
If they work, they should cut the muscle trigger - and release tension - thus relieving pain - and referred pain. There is a lot to read on myofacial pain trigger point injections.. and Janet Travells work online if you do a search. She is famous for her 2 volume medical texts - The Trigger Point Mannual.
Hope that was a little helpful, Robyn
