Trigger points are tight knots of muscle that won’t relax. Medication is injected directly into the muscle to relax it and ease the pain.
A trigger point injection will take about 30 minutes.
You will be positioned on your back or stomach on an x-ray table. The area to be injected will be cleansed with an antiseptic solution. After massaging the area, anesthetic will be injected into the knot to relieve the pain.
A summary of the procedure and findings will be sent to your healthcare provider.
Your activity level will vary depending on the location of the trigger point injection. Instructions will be given regarding any activity restrictions.
You may feel pain relief within minutes of the procedure. The injection can provide pain relief for days, weeks or months. You may need more than one injection.
For two to three days after the injection you may feel soreness or tenderness at the needle insertion site. You can use an ice pack for up to 15 minutes per hour to relieve any discomfort.
