What Is a Trigger Point Injection?
A trigger point injection is a minimally invasive medical procedure used to treat painful muscle knots, known as trigger points, that can cause localized or referred pain. At Cherry Medical, this procedure is performed by experienced neurologists as part of a comprehensive pain management approach.
During the injection, a small amount of medication (such as a local anesthetic, saline solution, or in some cases a corticosteroid) is injected directly into the affected muscle. The goal is to relax the muscle, reduce inflammation, and interrupt pain signals sent to the nervous system.
How Long Does a Trigger Point Injection Last?
At Cherry Medical, the duration of pain relief from a trigger point injection can vary based on each patient’s condition and treatment plan. This procedure is designed to relax tight muscle fibers, reduce inflammation, and calm overactive pain signals in the nervous system. While some patients experience immediate improvement, others notice gradual relief over time. Understanding how long the effects last helps patients set realistic expectations and better plan their recovery.
Typical duration of effects includes:
- Pain relief beginning within minutes to a few hours after the injection
- Continued improvement lasting several days to several weeks
- Longer-lasting relief, sometimes several months, when combined with physical therapy and lifestyle modifications
