Trigger Point Injections
What are Trigger Point Injections?
Trigger points are areas where muscle spasms have formed “knots” in muscle or fascia tissue. Trigger points can irritate nerves around them, and they can cause referred pain. Referred pain is pain that is experienced in a location different from the source of the injury. So if you have a trigger point in your neck, it can cause you to feel a tingling, numbness, or painful sensation in your arm or hand.
A trigger point injection is an outpatient procedure where medication is injected directly into the trigger point for pain relief. Depending on the underlying cause of the trigger point, a single injection may alleviate the problem, while recurring injections may be required to manage chronic pain.
To reduce injection pain, a numbing spray is used. Trigger point injection appointments are outpatient, and the entire procedure takes only minutes to perform. Side effects are rare and may include post-injection pain or fat shrinkage near the injection site.

Trigger points are the cause of many types of pain. Trigger point injections may be appropriate for numerous conditions, including:
- Tension headaches
- Chronic pain
- Myofascial pain
