Trigger points are commonly referred to as muscle knots. They are areas in the tendons and muscles that are tender to the touch and can become inflamed, causing pain. During a trigger point injection, the doctor inserts a small needle into the trigger point and inactivates it using an anesthetic and corticosteroid. This procedure relaxes the muscle and provides pain relief. More than one trigger point injection can be delivered in one visit.
What conditions does it treat?
Trigger point injections offer relief from myofascial pain syndrome, a muscle disorder where trigger points are often a major cause of pain. It can also relieve pain from tension headaches, fibromyalgia, and pain felt by muscle groups in the arms, legs, lower back, and neck.
What can I expect afterward?
Your pain relief should begin right away following the trigger point injection. You may feel soreness at the injection site that goes away after a couple of days. Even though the medication wears off, you should still experience less pain than before. Every patient is different, but some experience pain relief for months following the injection.
