5 Conditions That Respond Well to Trigger Point Injections

Tight, painful knots in your muscles can do more than cause discomfort; if you’ve experienced this, you know all too well that they can also limit your movement, disrupt your sleep, and make everyday activities feel more challenging than they should.

These knots, known as trigger points, are areas of muscle that have become irritated or overactive. When they don’t release on their own, trigger point injections can help relax your muscles and reduce pain.  

At Pain Medicine Group in Oviedo and Sarasota, Florida, Mauna Radahd, MD, Jason Tse, DO, and Morgan Callahan, MD, use trigger point injections to help treat muscle-related pain. Here’s how these injections work and five conditions that respond well to them.

What are trigger point injections?

These injections usually combine a local anesthetic with an anti-inflammatory medication. We administer trigger point injections directly into the tight muscle band, which helps:

• Relax your muscle
• Reduce inflammation
• Interrupt pain signals

The result is often twofold: improving your mobility and decreasing your pain.

5 conditions that respond well to trigger point injections

These injections can help address trigger points from both acute soft tissue trauma and microtraumas from overuse. You might consider getting a trigger point injection if you have:

1. Myofascial pain syndrome

This condition can cause chronic muscle and fascia pain. Myofascial pain syndrome also causes “hyperirritable” trigger points that can cause both local and referred pain.

For patients with chronic myofascial pain syndrome, the symptoms can last for six months or more. Not surprisingly, this is one of the most common reasons for trigger point injections. 

2. Tension headaches

Tight muscles in your neck, shoulders, and upper back can contribute to tension headaches. Treating the trigger points can help reduce both the frequency and intensity of your headaches.

3. Neck and shoulder pain

Repetitive strain, poor posture, or stress can lead to persistent tightness in your neck and shoulders. In some cases, muscle tension can develop alongside conditions like a pinched nerve, including radiculopathy.

Trigger point injections help relax these tight muscle bands, which can reduce pain and improve your range of motion. 

4. Low back pain 

Muscle-related low back pain often involves trigger points that don’t respond fully to stretching or rest alone. Injections can help relieve these stubborn areas of tension.

5. Fibromyalgia

Fibromyalgia is a complex condition that causes widespread musculoskeletal pain, fatigue, and tenderness. While trigger point injections aren’t considered a first-line treatment, some studies suggest that they may provide short-term relief in specific, localized areas of muscle pain. 

For example, injections into particularly painful trigger points can temporarily reduce tenderness and improve comfort in targeted regions. 

However, because fibromyalgia affects the body more broadly, injections are typically used as part of a larger treatment plan rather than a standalone solution. If you have fibromyalgia, we may also recommend medications such as pregabalin or gabapentin.

What to expect during a trigger point injection

Administering trigger point injections typically takes just a few minutes. 

We first identify the affected muscle and then insert a small needle directly into the trigger point. Most people feel only brief discomfort, followed by a release of tension in the area.

You can usually return to normal activities shortly after your appointment.

When to consider trigger point injections

Muscle pain doesn’t have to be something you just live with. If you’ve been dealing with persistent muscle pain that hasn’t improved with rest, stretching, or over-the-counter treatments, trigger point injections may be a helpful next step.

They’re especially useful when pain is localized and tied to specific muscle knots.
