Trigger point injections are performed by a range of healthcare providers, from primary care physicians to pain management specialists. The procedure is common enough that you don’t necessarily need a referral to a specialist, though the right provider depends on what’s causing your pain and how long you’ve been dealing with it.
Providers Who Perform Trigger Point Injections
Primary care doctors are often the first providers to diagnose and treat myofascial pain with trigger point injections. Many family medicine and internal medicine physicians perform these injections routinely in their offices, especially for straightforward cases of muscle pain in the neck, shoulders, or back.
Pain management specialists are another common choice, particularly if your pain is chronic or hasn’t responded to initial treatment. These are typically physicians who completed additional training (a fellowship) in managing complex pain conditions. They work in dedicated pain clinics and outpatient centers where trigger point injections are a regular part of their practice.
Beyond those two categories, several other types of providers perform the procedure:
- Physiatrists (physical medicine and rehabilitation doctors) specialize in musculoskeletal conditions and frequently use trigger point injections alongside rehabilitation programs.
- Orthopedic doctors may offer injections when trigger points are contributing to joint or movement problems.
- Rheumatologists sometimes perform them for patients with widespread muscle pain conditions like fibromyalgia.
- Sports medicine physicians use them for athletes and active individuals dealing with muscle tightness or overuse injuries.
- Some chiropractors and nurse practitioners are trained and licensed to perform trigger point injections, though this varies by state.
Most trigger point injections happen in a regular office visit setting. You don’t need to go to a hospital or surgical center. The procedure itself takes only a few minutes per injection site.
How Providers Decide You Need One
A provider diagnoses a trigger point through a physical exam, not imaging. They press on the painful area looking for a tight band or knot in the muscle that produces a characteristic response: pain at the spot itself, pain that radiates to another area (called referred pain), and sometimes a visible twitch in the muscle when pressed. If they can feel a distinct tender knot that reproduces your pain pattern, that’s typically enough to proceed.
Common reasons patients end up getting trigger point injections include chronic or episodic headaches, jaw pain, back pain, reduced range of motion from muscle tightness, and groin pain. The injections are usually considered after stretching, physical therapy, or over-the-counter pain relievers haven’t provided enough relief on their own.
What Gets Injected
The injection typically contains lidocaine, a local anesthetic that provides immediate pain relief by numbing the muscle tissue. Some providers also add a small dose of cortisone, a steroid that reduces inflammation in the tight muscle fibers creating the trigger point. While the lidocaine works right away, the cortisone can extend the benefit by addressing the underlying inflammation that keeps the muscle locked in a painful cycle.
In some cases, providers use what’s called “dry needling,” where the needle itself is inserted without any medication. The needle’s mechanical disruption of the knotted muscle fibers can be enough to release the trigger point. The choice between a wet injection (with medication) and dry needling often comes down to provider preference and what has worked for you in the past.
What the Procedure Feels Like
The injection takes just a few minutes per trigger point. Your provider will locate the knot by pressing on the area, then insert a small needle directly into it. You’ll likely feel a brief cramping or aching sensation as the needle hits the trigger point, and you may notice the muscle twitch. This is actually a good sign, as it indicates the needle reached the right spot. The discomfort is short-lived, and the lidocaine begins numbing the area almost immediately.
You can typically return to normal activities the same day, though the injection site may feel sore for a day or two, similar to how a muscle feels after a flu shot. Applying ice or gentle heat can help with any post-injection soreness.
How Often You Can Get Them
There are limits on how frequently trigger point injections should be repeated. Medicare guidelines cap coverage at three injection sessions per rolling 12-month period. The American Society of Interventional Pain Physicians recommends a slightly different approach: during an initial diagnostic phase, injections can be given weekly (up to four times per year), but once you move into ongoing treatment, sessions should be spaced at least two months apart and not exceed six per year. To continue receiving injections in that maintenance phase, you should be experiencing at least 50% improvement that lasts six weeks or longer after each session.
Providers also avoid injecting multiple muscle groups in completely different body regions during the same visit, as this isn’t considered medically necessary. If you have trigger points in both your neck and lower back, for example, those would typically be addressed in separate appointments.
Risks and Who Should Avoid Them
Trigger point injections are considered low-risk. The most common side effects are temporary soreness at the injection site and minor bruising. In rare cases, complications can include skin infection at the injection site, a hematoma (a pocket of blood in the muscle), or a vasovagal response where you feel lightheaded or faint during the procedure. For injections near the upper back or chest wall, there’s a very small risk of pneumothorax, which is when air leaks into the space around the lung.
In a study of over 12,000 patients who received intramuscular injections, abscess and hematoma occurred in 0.12% of cases, and bleeding complications in 0.07%. These are uncommon events, but they’re worth knowing about.
The procedure is not appropriate for everyone. If you have a bleeding disorder, are taking blood thinners, or have an active infection (either at the injection site or throughout the body), trigger point injections are contraindicated. Make sure your provider knows about any of these conditions before scheduling the procedure.
Insurance Coverage
Most insurance plans, including Medicare, cover trigger point injections when they’re documented as medically necessary. The procedure is billed under two codes: one for injections into one or two muscles, and another for three or more muscles. Medicare limits reimbursement to three sessions per rolling 12 months regardless of which code is used. Private insurance policies vary, so it’s worth checking your specific plan’s coverage limits before your appointment, especially if you anticipate needing multiple sessions.
