Chronic pain can be a debilitating condition that affects millions of people worldwide. Pain can make it difficult to concentrate, to work, and even to perform everyday activities. For those who suffer from chronic pain, finding relief can be a challenge. While there are medications and other treatments that can help, not all of them work for everyone. However, one treatment option that has been shown to be effective for many people suffering from chronic pain is trigger point injections.

What Are Trigger Points?

Trigger points are hyperirritable spots within a tight band of muscle that can cause pain, discomfort, and even weakness. These areas can be localized or referred, meaning they can cause pain in other parts of the body as well. Trigger points are commonly found in the neck, shoulders, back, and hips.

How Do Trigger Point Injections Work?

Trigger point injections work by injecting a small amount of medication directly into the trigger point. The medication typically includes a local anesthetic, such as lidocaine, and a steroid like cortisone. The injection aims to break down the trigger point, reducing pain and inflammation and enhancing range of motion.

What to Expect During a Trigger Point Injection?

The procedure is relatively straightforward and usually takes only a few minutes. The doctor will locate the trigger point, clean the skin, and apply a local anesthesia. Then, using a small needle, the doctor will inject the medication directly into the trigger point. Most patients report minimal discomfort during the procedure.

What Conditions Can Trigger Point Injections Help With?

Trigger point injections can be helpful for a variety of conditions, including:

  • Back pain
  • Neck pain
  • Headaches and migraines
  • Fibromyalgia
  • Sciatica
  • Myofascial pain syndrome
  • Tension headaches

Benefits of Trigger Point Injections

Trigger point injections offer several benefits, including:

  • Fast-acting relief
  • Effective in reducing pain and inflammation
  • Enhancing range of motion
  • Minimal side effects
  • Can reduce reliance on medications

Who Should Get Trigger Point Injections?

Trigger point injections are suitable for individuals who suffer from chronic pain that has not responded to other treatments, like medications or physical therapy. The injections can also be helpful for people who prefer a non-surgical, minimally invasive option.

Risks and Side Effects

As with any medical procedure, there are potential risks and side effects to consider. They are rare, but the risks include bleeding, infection, and nerve damage. The side effects of trigger point injections may include soreness, bruising, and temporary weakness in the injected muscle.

Post-Injection Care

After the injection, the doctor will recommend that you rest for the day. You should avoid strenuous exercises and weightlifting for at least 48 hours. You may experience mild soreness or redness at the injection site, and you can use ice to reduce these symptoms.

Frequency of Trigger Point Injections

The frequency of trigger point injections depends on the individual’s condition and progress with the previous injections. Patients may require multiple sessions to achieve maximum relief. Most doctors recommend a series of injections every two to four weeks.

Cost of Trigger Point Injections

The cost of trigger point injections varies depending on the provider, location, and insurance coverage. Most insurance plans cover the cost of the procedure, and patients can expect to pay a copay or out-of-pocket deductible.


Trigger point injections offer a fast and effective solution for chronic pain relief. The injections provide a minimally invasive, non-surgical option for those who have not responded to other treatments. While there are potential risks and side effects, they are rare. The procedure is generally safe, with minimal downtime. If you suffer from chronic pain, talk to your doctor about whether trigger point injections may be an option for you.

The procedure isn’t recommended for pregnant or breastfeeding women, people taking blood thinners, or those with an infection near the injection site. Always consult with your doctor to determine if the procedure is right for you.
