Trigger Point Injections at Advanced Health Chiropractic

Trigger point injections are a well-established medical procedure used to treat painful, tight bands of muscle tissue known as trigger points — commonly called "muscle knots." These hyperirritable spots develop when muscle fibers contract and won't release, creating localized pain that often radiates to other areas of the body. A trigger point in the upper trapezius, for example, can send pain up the neck and into the head, mimicking a tension headache. One in the piriformis can produce symptoms that feel nearly identical to sciatica.

At Advanced Health Chiropractic, trigger point injections are one of the most frequently used tools in our care plans. We incorporate them into the majority of our treatment protocols because they address a layer of dysfunction that chiropractic adjustments and physical therapy alone sometimes can't fully resolve. When a muscle is locked in spasm, it pulls on the joints it attaches to, limits range of motion, and creates a pain cycle that reinforces itself. Breaking that cycle with a precise injection allows the other treatments in your care plan to work more effectively.

Our injections use lidocaine and saline — no steroids, no opioids. The lidocaine provides immediate local pain relief, while the saline helps mechanically disperse the contracted muscle fibers and flush the area. The goal is simple: deactivate the trigger point, restore normal muscle tone, and eliminate the pain pattern it was causing.

A trigger point forms when a small cluster of muscle fibers enters a sustained contraction — essentially a cramp that doesn't release on its own. This contracted area restricts blood flow to the tissue, which causes a buildup of metabolic waste products and inflammatory chemicals. Those chemicals sensitize the local nerve endings, which causes pain and can refer pain to distant areas through predictable patterns that have been well-documented in clinical literature.

During a trigger point injection, a fine needle is inserted directly into the trigger point. The physical disruption of the needle itself helps break apart the taut band of muscle fibers. The lidocaine immediately numbs the area and interrupts the pain signal, while the saline solution helps disperse the contracted tissue and flush out the accumulated inflammatory chemicals. This combination — mechanical disruption, anesthetic relief, and chemical flushing — is what makes trigger point injections more effective than massage or stretching alone for chronic, established trigger points.

The result is often immediate: the muscle relaxes, range of motion improves, and the referred pain pattern diminishes or disappears. For many patients, this is the moment they realize their headache was actually coming from their neck, or their hip pain was originating in a gluteal muscle.

Trigger point injections are often recommended for patients experiencing:

• Chronic muscle pain that hasn't responded fully to chiropractic adjustments, massage, or stretching alone
• Tension headaches and cervicogenic headaches caused by trigger points in the neck, upper back, and shoulder musculature
• Myofascial pain syndrome — widespread or regional pain driven by multiple active trigger points
• Neck and upper back pain with persistent muscle tightness that limits range of motion
• Low back pain involving spasm in the paraspinal, quadratus lumborum, or gluteal muscles
• Referred pain patterns — pain that radiates from a muscle to a seemingly unrelated area, such as shoulder trigger points causing arm pain
• Post-injury muscle guarding — protective spasm that persists long after the initial injury has healed

Your doctor will identify the specific trigger points through palpation — pressing into the muscle to locate the taut band and reproduce your pain pattern. This is a critical step: the injection needs to be placed precisely into the trigger point to be effective. Once the trigger points are identified, the skin is cleaned, and a fine-gauge needle is inserted directly into each point.

You'll feel a brief pinch as the needle enters the skin, followed by a sensation of pressure or a brief muscle twitch as the needle reaches the trigger point. That twitch — called a local twitch response — is actually a good sign. It confirms that the needle is in the right spot and that the trigger point is being deactivated. The lidocaine takes effect within seconds, and most patients report immediate relief at the injection site.

The entire procedure takes only a few minutes. There are no incisions, no sedation, and no recovery period. You can return to normal activity immediately, though we recommend avoiding intense exercise for the rest of the day. Mild soreness at the injection site for 24 to 48 hours is normal — similar to the feeling after a deep tissue massage. Trigger point injections are typically administered twice per week as part of your broader care plan, alongside chiropractic adjustments, physical therapy, or other treatments prescribed for your condition.

Many patients notice immediate improvement after their first session — reduced pain, less muscle tightness, and improved range of motion. However, chronic trigger points that have been present for months or years often require a series of treatments to fully resolve. The muscle has essentially learned to stay contracted, and it may take several sessions to retrain it to maintain normal tone.

Because trigger point injections are integrated into your broader care plan at Advanced Health Chiropractic, the results compound with each visit. The injections release the muscle, the chiropractic adjustment corrects the joint alignment that the muscle was pulling on, and the physical therapy exercises reinforce the new, correct movement patterns. This layered approach is why patients who've struggled with chronic muscle pain elsewhere often see lasting results here — we're addressing the trigger point itself, the structural issues that caused it, and the movement patterns that perpetuate it, all at the same time.

Do trigger point injections hurt?

Most patients feel a brief pinch when the needle enters the skin, followed by a moment of pressure or a muscle twitch as the trigger point is reached. The lidocaine provides immediate numbing, so any discomfort is short-lived — typically lasting only a few seconds. Some patients experience mild soreness at the injection site for 24 to 48 hours afterward, similar to the soreness you'd feel after a deep tissue massage. The vast majority of patients find the brief discomfort well worth the relief.

How often do I need trigger point injections?

At Advanced Health Chiropractic, trigger point injections are typically administered twice per week as part of a comprehensive care plan. The total number of sessions depends on the severity and duration of your condition, the number of active trigger points, and how your body responds to treatment. Most patients notice meaningful improvement within the first few sessions, and the treatment frequency tapers as the trigger points resolve and the supporting muscles strengthen through physical therapy.

What is injected during a trigger point injection?

We use a combination of lidocaine (a local anesthetic) and saline (sterile salt water). Lidocaine provides immediate pain relief by numbing the area, while saline helps mechanically disperse the contracted muscle fibers and flush out the inflammatory chemicals that have accumulated at the trigger point. We do not use steroids or opioids in our trigger point injections. This approach is safe, well-tolerated, and effective for the vast majority of patients.

Does insurance cover trigger point injections?

Many insurance plans cover trigger point injections when they are medically necessary, which is typically documented through your physical examination findings and diagnosis. Coverage varies by plan. Our team will help you understand your specific benefits and will provide transparent pricing of your policy coverage and for any portion that isn't covered by insurance.
