What Are Trigger Point Injections?
Trigger point injections are performed to treat painful muscle areas that contain “trigger points” or knots that form when muscles do not relax. These knots can usually be felt under the skin, and may twitch involuntarily. The trigger point may trap or irritate surrounding nerves causing pain in other areas of the body.
Trigger Point injections can be performed on many different muscle groups in the arms, legs, lower back, upper back, and neck. These injections are also sometimes used to treat pain from:
What happens during the injection?
One of our pain doctors will perform the procedure which usually takes 5 to 10 minutes. Patients remain awake during trigger point injections. A small needle will be inserted into the trigger point and a local aesthetic or local anesthetic with steroid will be injected. The injection of this medication inactivates the trigger point and alleviates pain.
What happens after the injection?
Immediately after the injection you will remain in our center for a short recovery period. A band-aid may or may not be placed on the injection site as it is done with a very small needle. Numbness in the area injected may last for a few hours after the procedure. The site that was injected may be sore for a few days, which can be alleviated by applying ice and/or heat. Stretching exercises and sometimes physical therapy following the injection can also help to alleviate pain.
