Trigger Point Injections

Trigger point injections (TPIs) are a medical treatment used to relieve muscle pain and tension caused by tight knots, known as trigger points. These trigger points can develop in muscles due to injury, overuse, stress, or underlying medical conditions. TPIs are commonly used to treat myofascial pain syndrome, fibromyalgia, and tension headaches.

We offer Trigger point injections — a safe and minimally invasive treatment that targets inflammation at the source. By reducing swelling and irritation, these injections can provide lasting relief and help you get back to living comfortably.

What Are Trigger Point Injections?

Trigger point injections (TPIs) are a minimally invasive treatment used to relieve pain caused by trigger points—tight, painful knots in the muscles.

TPIs involve the injection of a small amount of medication, such as a local anesthetic or corticosteroid, directly into the affected muscle to alleviate pain and improve mobility. In some cases, dry needling (using a needle without injecting medication) is also performed to break up the trigger point.

How Do Trigger Point Injections Work?

When a muscle becomes overly contracted or irritated, it can form a painful knot that restricts blood flow and causes discomfort. This can lead to referred pain, meaning the pain extends beyond the trigger point itself.

Trigger point injections help by:

Disrupting the pain cycle – The injection numbs the area and reduces nerve sensitivity.
Improving blood circulation – The treatment allows fresh oxygen and nutrients to reach the muscle.
Relaxing the muscle – This helps restore normal function and range of motion.
Reducing inflammation – If a corticosteroid is included, it helps decrease swelling in the muscle tissue.

Conditions Treated with Trigger Point Injections

TPIs are commonly used to manage various pain conditions, including:

Myofascial Pain Syndrome

A chronic pain condition involving multiple trigger points in the muscles.

Fibromyalgia

A disorder that causes widespread musculoskeletal pain, often associated with trigger points.

Tension Headaches

Trigger points in the neck, shoulders, and upper back can contribute to chronic headaches.

Chronic Back and Neck Pain

Tight muscles in these areas can lead to persistent discomfort and limited movement.

What to Expect During the Procedure

The procedure is relatively quick and is usually performed in a doctor’s office.

Preparation: Before the Procedure

Interventional Pain Management, Pain Management Solutions, Chronic Pain Treatment, Nerve Pain Management, Spinal Cord Stimulator, Non-Surgical Pain Relief, Medial Branch Nerve Blocks, Joint Injections For Arthritis, Herniated Disc Treatment, Pain Relief For Muscle Strain, Pain Alleviation

Medical Evaluation

Your doctor will perform a comprehensive history and physical exam, which may include imaging tests such as X-rays or MRIs, to confirm the diagnosis and plan the procedure.

Medications

Inform your physician about any medications or supplements you are taking, as certain medications, like blood thinners, may need to be paused before the procedure.

Fasting

This is not necessary prior to joint injection.

Clothing & Transportation

Wear loose, comfortable clothing and arrange for someone to drive you home after the procedure.

Consent & Instructions

You will review and sign a consent form and receive detailed guidance on what to expect before, during, and after the procedure.

During the procedure:

The procedure usually lasts about 5 minutes, depending on the number of trigger points being treated.

Sterile Preparation

The area for injection will be thoroughly cleaned with antiseptic solution to prevent injection.

Anesthesia

A small amount of steroid and numbing medication will be injected into the tigger point and dry needling technique will be used to break up the knot. Medication can be deferred if the patient prefers and only the dry needling is done.

Bandage

After the injection is complete, the area is cleaned, and a bandage is applied to protect the site.

After the Procedure: Post-Care

Monitoring

You will rest in a recovery area while your are monitored for about 15 minutes.

Pain Relief

Many patients experience immediate or significant pain relief, though many also do not feel the full benefits until 2 weeks. Mild discomfort at the injection site is normal and should subside within a few days.

Activity Restrictions

No restrictions.

Follow-Up

A follow-up appointment will be scheduled to review the results of the injection and discuss the next steps for long-term pain relief.

Types of Trigger Point Injections

There are different types of TPIs, depending on the medication used:

Local Anesthetic (e.g., Lidocaine or Bupivacaine): Provides immediate pain relief by numbing the area.
Corticosteroids: Help reduce inflammation and provide longer-lasting relief.
Saline Injections: Used to break up the trigger point without medication.
Dry Needling: Involves inserting a needle without injecting any medication to stimulate the muscle and release the knot.

What Are the Risks or Side Effects of Trigger Point Injections?

While TPIs are generally safe, some potential side effects may occur. Patients may experience temporary soreness, bruising, or swelling at the injection site. Mild dizziness or lightheadedness can also occur, but these symptoms are usually brief and resolve on their own. In rare cases, muscle weakness or numbness may develop, though this is typically temporary and subsides within a short period. Injections near the lungs also pose a risk for pneumothorax.

Another potential risk is infection, though this is extremely rare when the procedure is performed in a sterile environment. Patients with underlying medical conditions, such as bleeding disorders or active infections, should consult their doctor before undergoing trigger point injections to ensure the treatment is safe for them.

These risks will be thoroughly discussed during your consultation appointment.
