Trigger Point Injections are a rapid, outpatient procedure used to treat painful, knotted, or tight muscle "knots" (myofascial trigger points) by injecting a local anesthetic, often combined with a steroid, into the affected area. They are highly effective for relieving, chronic pain, providing relief that can last for about a month or longer.
Key Aspects of Trigger Point Injections:
Procedure & Duration: The procedure is quick, typically taking 15 to 20 minutes in a doctor's office depending on patient prognosis and level of treatment necessary.
Mechanism: The needle insertion breaks up the muscle spasm, while the medication (e.g., lidocaine, corticosteroid) relaxes the muscle, increases blood flow, and reduces inflammation.
Conditions Treated: TPI is commonly used for chronic pain in the neck, lower back, shoulders, and arms, as well as tension headaches and fibromyalgia.
Recovery & Results: There is generally no downtime, though minor soreness at the injection site may last up to 2 days. Pain relief often begins within 24–72 hours, with effects potentially lasting for months. Again dependent on patient and their level of participation in treatment protocols.
Frequency: Injections can be repeated as needed, sometimes as frequently as every 3 months.
Risks & Side Effects: TPI is considered safe, with minimal side effects. Potential, rare risks include infection, bleeding, or bruising at the site.
Trigger point injections are effective in managing persistent muscle pain and improving mobility. They are frequently used when other, more conservative treatments (like physical therapy) have not provided sufficient relief.
