What are Trigger Point Injections?

Trigger point injections are a treatment used to relieve pain in specific areas of your muscles. These areas, known as trigger points, can feel like tight knots under your skin and are often painful when pressed. Trigger points can cause discomfort in the neck, back, shoulders, and other parts of the body.

How Do Trigger Point Injections Work?

Trigger point injections involve injecting a small amount of anesthetic and sometimes a steroid into the trigger point. This helps to relax the muscle and relieve pain. The anesthetic works by numbing the area, while the steroid can reduce inflammation.

When Are Trigger Point Injections Used?

Trigger point injections are used when other treatments like physical therapy, massage, or medications haven’t provided enough relief. They are especially helpful for:

• Myofascial pain syndrome
• Tension headaches
• Fibromyalgia
• Chronic pain in the neck, shoulders, back, or limbs

Preparing for Your Trigger Point Injection

Before the procedure, your doctor will review your medical history and current medications. Be sure to inform your doctor of any allergies or health conditions. You may need to avoid certain medications before the injection.

The Injection Process

The procedure is done in a clinic setting. Here’s what to expect:

1. Positioning: You will lie down or sit in a comfortable position, depending on the location of the trigger point.
2. Cleaning: The skin over the trigger point will be cleaned with an antiseptic solution.
3. Injection: Using a small needle, the doctor will inject the anesthetic and possibly a steroid directly into the trigger point.
4. After the Injection: A small bandage will be applied, and you might be asked to move the affected muscle to help distribute the medication.

After the Injection

After the procedure, you may feel immediate relief from pain. It’s normal to have some soreness at the injection site for a day or two. Your doctor will give you specific instructions on how to care for the injection site and when to resume normal activities.

Possible Side Effects

Some potential side effects of trigger point injections include:

• Temporary soreness or bruising at the injection site
• Lightheadedness or dizziness
• Allergic reaction to the medication (rare)
• Infection (very rare)
