Trigger Point Injections

Information may not be reliable

Trigger point injection is used to treat extremely painful areas of muscle. Normal muscle contracts and relaxes when it is active. A trigger point is a knot or tight band of muscle that can be felt under the skin and forms when muscle fails to relax.

The trigger point can irritate surrounding nerves and cause referred pain felt in another part of the body. Over time scar tissue, loss of range of motion, and weakness may develop.

Trigger Piont Injection is taken approximately 30 minutes. Before performing Trigger Point Injection, the physician may give the patient a local anesthetic to prevent pain from needle penetration.

A small needle is inserted into the trigger point and steroid-anesthetic mixture is injected. Injection of medication inactivates the trigger point and thus alleviates pain. Sustained relief usually is achieved with a brief course of treatment. The injection may cause a twitch or pain that lasts a few seconds to a few minutes.
