Trigger Point Injections

Many people have heard of a procedure called "dry needling" but are not familiar with trigger point injections, which are used to treat what most people believe is "TMJ," when the pain is actually caused by muscles. Trigger point injections and dry needling are the same procedure with one major difference. Trigger point injections involve the use of 1% plain lidocaine to numb the area being treated, which makes the procedure more comfortable whereas nothing is injected with dry needling. The use of lidocaine provides immediate feedback that the diagnosis is truly muscular in origin. If the trigger point injection reduces or eliminates the pain, then the source of the pain is the local muscle that was injected. However, it is not the lidocaine that provides the long-term relief. It is the needling that is done. Needling involves poking the local muscle with a very thin needle for 30 to 60 seconds, which intentionally induces inflammation into the area, which the body will repair in 24-48 hours. This is not a painful procedure as it is more of a sensation but it is common to be sore for a day or two after the procedure.

The protocol I follow in my Beverly Hills office we follow in our practice is to try trigger point injections first and see what type of relief is provided. The relief can range from "one and done," meaning the pain does not return to the procedure providing a benefit but only for about a week. If there is a benefit but it is only one week, then I repeat the procedure again. The second round can set the pain free, last a few months or again last as short as a week. If the pain is relieved but only for about a week, I will use Botox at the third appointment. The benefit from the Botox also varies from setting the pain free to lasting two to three months. Some patients get a longer relief with the second round of Botox and some need Botox every three months.

It is difficult to "see" the benefit of trigger point injections with facial muscles but the benefit from the treatment I provided below to one of my residents is clearly visible. She presented with a very stiff neck and she could not move her head very much from side to side. The trapezius (shoulder) and splenius capitis (back of neck) muscles were in severe contraction, which you can see in the top row with the upper right outlining the contraction areas. I did trigger point injections using 1cc 1% lidocaine into several locations. You can see the injection sites for the trapezius, which are identified with the red numbers on the bottom right. Notice the relaxed lines of the trapezius in the red lines in the bottom right. She had full mobility after these injections.
