Trigger Point Injection

What is a trigger point injection?

A trigger point injection can help soothe muscle pain, especially in your arms, legs, lower back and neck. It also can be used to treat fibromyalgia, tension headaches and myofascial pain.

Trigger points are painful “knots” in your muscles. They form when a muscle can’t relax. Sometimes you can feel these knots when you rub your muscle.

Injecting small amounts of anesthetic and steroid into the trigger point can help alleviate the pain.

How is a trigger point injection done?

You will sit or lie down for the procedure. Your doctor will press on your muscle to locate the area where you have pain. Then, he or she will insert a small needle into the area and inject a mixture of anesthetic and steroid.

You can have several trigger points injected during one visit to your doctor’s office. The procedure only takes a few minutes.

What are the risks?

The risk of complication from a trigger point injection is very low. Complications such as bleeding and infection at the injection site are uncommon. However, you may have temporary soreness or numbness at the injection site.

What happens after the procedure?

After a trigger point injection, you can actively use your muscle. However, you should avoid strenuous activity for the first few days.

Is trigger point injection right for you?

Trigger point injection may be right for you if your muscle pain has not improved with other treatment, including pain medication and physical therapy.
