Reduces Inflammation for Knotted or Tight Muscles
Trigger Point Injection Facts & Information
First, what is a trigger point? A trigger point is a knotted or tight area of muscle that can be felt under the skin and, when pressure is applied, often refers (or “triggers”) pain to another part of the body.
Trigger point injections contain medication designed to break the pain cycle allowing a patient to more effectively participate in a rehabilitative program. Trigger point injections successfully treat many muscle groups, especially those in the arms, legs, lower back, and neck – additionally, they are often used for fibromyalgia and tension headaches.
Trigger points are diagnosed by a thorough physical exam in which the physician palpates muscles for tender areas over taut bands and knots. Imaging tests such as x-rays or MRI cannot detect a trigger point, but may be helpful in revealing an underlying condition.
How Do Trigger Point Injections Help?
A trigger point injection delivers a mixture of medications to reduce inflammation. The injection relaxes the muscle, which improves blood flow and promotes healing. If you have more than one trigger point, you may have different muscles injected during the same treatment session. The injection is well tolerated because a local anesthetic is applied to the skin to numb any pain.
How Long does the Procedure Take?
Trigger point injections are safely performed on an outpatient basis. The procedure typically requires 15 minutes, including preparation time, and is followed by a short period of observed recovery time.
How Often Should this Procedure be Done?
Initially, the injections may be performed every one or two weeks for several weeks, but are usually limited to one session every two months if they are performed as maintenance treatment.
What are the Expected Results?
Trigger point injections are very safe. You may feel some injection site tenderness as the local anesthetic wears off. It may take a few days for the anti-inflammatory action of the medicine to take effect. The main benefit of the trigger point injection is to loosen muscle groups, thereby improving your progress in a physical rehabilitation program.
For even longer lasting benefits, advanced, regenerative procedures, such as prolotherapy and platelet rich plasma (PRP) therapy, may be recommended. These innovative techniques promote healing and the potential for permanent improvement.
